GROWONIX DDP-60 Electronically Controlled Water Delivery Pump

The DDP-60 is a high-performance water delivery pump designed for non- aggressive water or water not containing solid particles. Its reverse osmosis filtration method ensures that waste water is contained within the pressurized chamber while pure solvent (ROwater) is allowed to pass through the membrane. With a 60 GPM water flow rate and the ability to stack multiples for added flow rate, this pump is perfect for big water transfer and as a booster for CX series RO systems.

Features:

• 60 GPM water flow rate
• Stack multiples for added flow rate
• Auto Shut-Off Circuitry under 0.7GPM
• High-pressure cutoff
• Ultra-quiet and compact
• Built-in the U.S.A.

Product Usage Instructions

Before using the DDP-60, ensure that it is installed correctly following these instructions:

Installation:

1. Install the suction line as short and straight as possible with minimal bends. The internal diameter of the suction pipe must be equal to or greater than the ports of the pump.
2. If the suction lifts over 13 ft, use a larger suction pipe.
3. Ensure all connections are completely sealed using thread tape only.

Operation

1. Connect the pump to a non-aggressive water source or one that does not contain solid particles using the instructions provided in the user manual.
2. Turn on the pump and adjust the pressure as needed.
3. Monitor the water flow rate and ensure that the pump does not operate under 0.7GPM, which can trigger the auto shut-off circuitry.
4. If using multiple pumps, connect them in parallel to double the flow rate.

Note : The warranty does not cover any damages caused by incorrect installation or operation. Do not apply any bonded material or glue to cover the suction or discharge ports of the pump.

INTRODUCTION

OUR MISSION
Durability, Reliability, Efficiency, Purity, and Conservation form the foundation on which we design and build all of our products. Consistent and superior quality sets us apart from other manufacturers and increases our value to you – our customer. Whether you are a hydroponics hobbyist, serious enthusiast, or large-scale gardener, GrowoniX is committed to bringing you the best solution for water purification systems.

WHAT IS REVERSE OSMOSIS?
Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. This filtering process ensures that the solute (waste water) is contained within the pressurized chamber while the pure solvent (RO water) is allowed to pass freely through the membrane.

TUNED FOR GROWING – IN TUNE WITH OUR CUSTOMERS
Traditional RO systems have waste ratios of approximately 4:1, which means there are 4 gallons of waste water produced for every 1 gallon of purified water. GrowoniX line of water filters achieve waste ratios of 2:1 with all 200-400 GPD systems, and an astounding 1:1 ratio with the 600-1000 GPD systems.
GrowoniX has created a complete product line that will address the needs of hydroponic operations of all sizes. Our filters will significantly reduce your water use while dramatically increasing your yields.

INSTRUCTIONS

Please read all instructions carefully before installing your new DDP-60, as failures caused by incorrect installation or operation are not covered by the warranty.

PRODUCT

The DDP-60 is designed for the pumping of non-aggressive water, or water not containing solid particles.

OPERATING CONDITIONS:

• Ambient temp : Max. +104°F (40°C)
• Liquid temp : +39°F(4°C)-+104°F(40°C) Max.
• System pressure : Max. 120 PSI
• Relative humidity : Max. 85%(RH)

INSTALLATION

• The pump foundation should be rigid enough to absorb any vibration from the motor, and the pump should be securely bolted to the foundation.
  It is recommended that the installer provides an adequate draining system to avoid damage in case of leakage, particularly when installed indoors. When it is installed

• Outside, it should be covered by weather-proof housing and well-ventilated to allow motor heat to escape.

• Connect the suction pipe to the side and the discharge pipe on the top.( See Fig 1 )

• When it is installed with a water heater, a check valve should be installed between the pump (discharge) pipeline and the water heater (suction) to avoid high-pressure steam backflow.

• It is required to shut off the pump when the liquid source is unavailable; although it has the dry run cut-off function.

• Please cut out the center of the rubber gasket inside the inlet and outlet flanges as it will block the water flow.(See Fig 2)

• Regular maintenance requires to open the prime cover in order to access the check valve.

• DO NOT apply any bonded material (such as silicon, glue etc) to seal the chamber cover ( See Fig 3).

PIPING

1. The suction line should be installed as short and straight as possible, with a minimum of bends. The internal diameter of the suction pipe must be equal to, or greater than the ports of the pump.
2. The connection between the suction line and pump must be airtight, and the suction pipe must be positioned so it has an upward slope to the pump (thus avoiding the formation of air pockets).
3. If it is likely the water supply may contain solid particles, such as leaves and sand, a filter should be installed on the suction line.
4. If hose is used as the suction pipe, it must be non-collapsible.
5. To minimize pressure drop, the discharge pipe should be at least the same size as the discharge port of the pump.
6. For long suction pipes or high suction lifts over 13 ft, the suction pipe should be of greater diameter than the suction port.
7. Ensure all connections are completely sealed using thread tape only.

CONNECTIONS TO WATER SOURCE

FLOODED SUCTION- FROM WELL SYSTEM

With gravity feed to the pump, there are no special adjustments to be made.
See Fig. 4 below for recommended layout. Simply make necessary plumbing connections and apply power.

The pump is ready to use

FLOODED SUCTION- FROM CITY WATER SUPPLY

Directly applied city pressure can exceed the pump operating pressure and damage the pump. The maximum inlet pressure should not exceed 45 PSI. Any greater incoming pressure is required to install a pressure-reducing valve on the suction side of the pump. In some areas where local codes restrict maximum home pressure, a pressure-reducing valve is also required on suction to lower the inlet pressure.

The chart below shows the applicable settings for the pressure-reducing valve:

SUCTION LIFT- BELOW-GROUND WATER SOURCES

This connection does not require any adjustment. Whenever the installation position of the pump is higher than 3ft above the lowest water level, a foot valve must be installed on the end of the suction pipe.

WARNING

The pump is not designed for continuous operation under low discharge flows such as slow closing float valves, and slow running taps. Under this application, please install an extra tank ( typically 2-3 gallons) to avoid “cycling”. (Fig 6)
Please set the extra pressure tank pressure the same as the activation pressure. Leaking discharge lines and leaking taps will damage the unit causing the pump to repeatedly start and stop.
Note : Optional external water pressure tank can be used to decrease the on/off cycle rate of the pump system, which can extend the life of the pump.

ELECTRICAL
This mark located outside the connection box is a warning for an electrical hazard.

1. Ensure the mains voltage is the same as the value shown on the motor plate and that the pump is safely connected to the ground/earth.
2. The single-phase models are supplied with a plug and lead and can be connected directly to the main supply. The 3 phase models should hook up with a circuit breaker

WARNING
Risk of electric shock – This pump has not been investigated for use in swimming pools or marine areas. To reduce the risk of electric shock, connect only to a properly grounded, grounding-type receptacle Before the operation, please ensure the voltage is correct and the circuit breaker and grounding connectors are all connected in accordance with local regulations.

STARTING

Before starting, the pump must be primed. For installation with no inlet pressure, please follow the procedure as shown in Fig.8.

1. For installation with inlet pressure, remove the priming plug and allow the water to flow into the priming chamber until all air is expelled.
2. The priming procedure should be repeated until all air is expelled and the pump delivers a full stream of water without bubbles.
3. The pump must always be checked for prime if not used for a prolonged period. It is imperative to fill the pump with liquid before the operation as dry running causes irreparable damage to the mechanical seal.
4. When a 3-phase motor is supplied, please ensure that the rotation is correct. You can switch any of the 2 wires to change the rotation.

PRECAUTIONS

1. The pump should be shut-down and the trouble corrected if the pump is running at speed and found to have any of the following problems:
2. No liquid discharged – Not enough liquid discharged
3. Excessive vibration – Motor runs hot
4. Do not allow the pump to continually start and stop (cycling) as this will reduce the motor life.
5. Cycling can occur on pressure units when the pressure tank pre-charge drops, or where there is a leak in the discharge plumbing

OPERATION & MAINTENANCE

Under normal operating conditions, the pump does not require any maintenance as long as the following points are observed.

1. Periodically check the condition of the check valve and strainer (if used).
2. If the pump is to be inactive for long periods, it should be rinsed thoroughly with clean water, then, drained and stored in a dry place. (t has to be pre-primed before start-up).
3. If the pump shaft is seized up after periods of inactivity, please place a screw driver from the motor end to rotate the shaft. It should free the pump shaft. (See Fig. 9) If this does not remedy the problem, the unit will need dismantling.
4. Pressure Tank air charge should be checked at regular intervals of every 6 months and after the pump has not been used for a prolonged period. To check the Pressure Tank air pressure, turn off the power, open a tap on the discharge line to release pressure from the pump, unscrew the black plastic cover and apply an accurate pressure guage to the valve as shown in Fig. 10. Pressure should be adjusted to the original pre-charge as follows:
5. DDP-60: 20psi (1.4 Kg/cm)

WHAT CAUSES THE DDP-60 TO START?

The DDP-60 has the built-in pressure switch and internal flow switch. Each of these can turn the pump on depending on water consumption.
The pump will start when:

The pressure is BELOW the pressure switch activation point. OR The flow rate is greater than 0.7 GPM.

WHAT CAUSES THE DDP-60 TO STOP?
The flow switch is designed to automatically stop the DDP-60 when flow drops to below 0.7 GPM. The DDP- 60 is programmed to stop after 8 seconds. In addition, the DDP-60 will be turned off in the event of dry-run or over temperature alarm.

WHAT IS THE PURPOSE OF THE BUILT-IN PRESSURE TANK?
The pressure tank comes from the factory pressurized at approximately 20 psi (with the pump pressure at zero). It is designed to minimize motor startup due to small flow demand or minor leak of the pipeline.

HOW IS THE DRY-RUN CONDITION DETERMINED AND THE PROTECTION PROVIDED?

The dry-run is defined when the motor is running AND the flow rate is less than 0.3 GPM AND when pressure is less than the pressure switch setting.

The protection is provided:

• When the pump is run dry 2 minutes, it will automatically shut off for 10 minutes and then attempts to restart.
• When all 3 attempts are failed, the pump will rest for 1 hour and then attempts to restart. This protection mode will be repeated until the water supply is back to normal.
• In case the pump is cycling (on-and-off repeatedly) due to small flow (less than 0.3GPM), air pocket in the system, air loss in the pressure tank or leak in the pipeline, the protection is provided:
• The pump will run for 8 seconds and stop for about 3 seconds. When the cycling mode repeats for 15 times consecutively, the pump will rest for 1 hour. Then it will start over the protection mode until the problem is corrected.

Note : The pump can be reset anytime by removing the power plug.

WHAT IS THE MAXIMUM INLET PRESSURE ALLOWED IN THE DDP-20?

The maximum internal system pressure allowed for DDP-60 is 120 psi.
The maximum inlet pressure when added to the DDP-60 pressure must not exceed 120 psi.
For example with a 40 psi inlet pressure supplied to the pump, internal system pressures can reach approximately 107 psi (67 + 40 psi). Additionally, if inlet pressures exceed the built-in pressure switch activation point (20 psi factory default), the pressure switch will be unable to function, and the ability to turn the DDP-60 on at low flow rates will be lost. In this situation, only the flow switch will be able to turn the DDP-60 on at flow rates above 0.7 gpm
