Technical data

Intended use

EP21594
This model of Electric booster pump enables to the maintenance of the required pressure n a pressurized pipeline. Thanks to this feature, the device can be used for water supply systems arrange? ment, for boosting water to low pressure in a water supply system, etc. It is possible to keep the pump operating also for a long period of time.

EP21592
This tool is designed for the irrigation and watering of green areas, vegetable beds, and gardens. for the operation of lawn sprinklers, for the drawing of water (with pre-filter) from ponds, streams, rain barrels, rainwater cisterns, and wells. for the supply of water to the house and for the pumping of clear water, rainwater, or light suds/service water.

This equipment has not been designed for use in commercial, trade, or industrial applications.

Installation

Install the equipment on a solid aid level surface. The pump must be placed as near as possible to the water level, while still maintaining a safe distance.

Receiver(EP21594)
To ensure a proper operation of the machine, it is necessary to maintain a certain pressure within the receiver (11). If the pressure drops, connect a car pump or compressor to the slide valve (13) and pump until the pressure within the receiver (11) reaches the minimum level for the pressure of the water supply system.

Connecting the suction hose(EP21594, EP21593, EP21592)
The diameter of the suction hose must not be smaller than that of the suction socket (4).
The suction hose is connected to the unit using a threaded connecting pipe (not available in this set), which is threaded into the threaded orifice of the suction socket (4). (F1)

The suction hose must be slightly angled up towards the suction socket (4) to avoid the formation of airlocks. Ensure that the suction hose connection is hermetic; this will prevent air blockin] and secure normal operation of the machine. Make sure that the suction hose is completely airtight and immersed in water.

Always fit a foot valve (c) (not available in this set) at the end of the suction hose. It is advisable to use a hose that is equipped with a filter element.

Installing a foot valve (c) [F2] (EP21594, EP21592)

1. flow rate adjustment gate valve (not supplied)
2. a non-return valve (not supplied)
3. foot valve (not supplied)

When the unit is used for pumping water from a basin or well which is located below the level of the pump, it’s necessary to mount a foot valve (c) at the end of the suction hose.

The foot valve (c) is a type of check valve which allows liquid to flow through it in only one direction and prevents backflow.

It should be connected to the end of the suction hose in order to prevent water from flowing back and totally empty the unit.

For an efficient operation of the pump, it is recommended to ensure that there is always some water available into the unit to prevent the pump from ‘deadhead’ operation or dry running.

WARNING! Do not operate the unit without water, in order to avoid engine meltdown, as a consequence of overheating.

1. Connect the foot valve (c) to the end of the suction hose. Use a hose clamp (not available in this set) to make the connection more secure.
2. Connect the suction hose to the pump by using the threaded connector and a hose clamp. Ensure that the connection is hermetic: this will prevent air blocking and secure the normal operation of the pump.
3. Dip the end of the suction hose with the mounted foot valve (c) into the water which should be pumped. The foot valve (c) must be completely below the water level.

Connecting the delivery hose(EP21594, EP21592)

The diameter of the delivery hose should be chosen to suit the flow rate and pressure required at the take-off points.

The delivery hose is connected to the unit using a threaded connecting pipe (not available in this set), which is threaded into the threaded orifice of the delivery socket (1). [F3]

It is advisable to fit a non-return valve (b) (not available in this set) – between the delivery socket (1) and flow rate adjustment gate valve (a) – to avoid dangerous water hammering in the event of the pump suddenly stopping.

This measure is compulsory if the delivery water column is over 20 meters.

Start-up

WARNING! Before the operation, it is necessary to fill the pump and suction hose or water pipe with water. Through the pressure line connection. Do not operate the unit without water in it

1. Plug into a shock-proof receptacle(120V/60Hz)
2. Before starting the pump, fill it completely with clean water through the pumping-in socket (3).
3. Connect the 1″ pressure hose to the pressure outlet using the nipple on the upper part of the pump.
4. Open all shut-off valves in the pressure line.
5. Empty any residual water in the pressure hose so that the air can escape when priming the pump.
6. Set the on/off switch to 0 positions.
7. Plug the power plug into the receptacle.
8. Set the on/off switch to 1 position.
9. Switch pump on complete intake can take 4-6 minutes, depending on the suction height_
10. Hold the pressure hose vertically approximately 1 meter above the pump until the pump is primed.
11. If the pump with the boosting system, the automatic pressure valve on the water tank switches off automatically when a pressure of 3 bar is reached. if the pressure drops to approximately 1.5 bar due to water consumption, the pump switches on automatically and restores maximum pressure.

Switching On/Off(EP21594, EP21592)
Switching On

1. Connect suction and delivery hose properly.
2. Fill the pump body with water through the water filler screw
3. Open the discharge line.
4. Connect the mains cable and set the on/off switch to the “ON” position.
5. The intake process starts automatically.

ATTENTION! When the garden pump is operating, the discharge line should be open in order to eliminate air from the host If the discharge line is closed, the pump may be seriously damaged by overheating after only 5 minutes of operation.

Switching Off
Set the on/off switch to the “OFF” position

ATTENTION! The pump should be primed again whenever it has not been used for a long period or when air has made its way into the system.

Operating Instructions

• The maximum pumping-out height must not exceed 8 meters.
• Grease and abrasive particles in water can lower the production of the pump, and also can make it inoperable.
• The end of the suction hose must always be immersed into the liquid, so as to not allow air to be sucked into the hose. If the hose’s weight is not sufficient and the hose is floating, then it is necessary to increase its weight artificially or lock it in.

Operation order

1. Attach hoses as described.
2. Submerge the suction hose into the basin of the water to be pumped.
3. Suspend the suction hose; this will prevent the machine from slipping down, as the hose weight will be taken by the suspension, not by the machine.
4. Unscrew the vent screw (2) and fill the machine with water. Screw the vent screw (2) back into the socket.
5. Connect the power cord to the power source and switch on the machine. If the machine does not start pumping within 3 minutes (due to air blocking, too high pumping height, too long hose), it must be switched off and the cause of the pumping failure must be eliminated. Then restart the machine.

It is necessary to control the unit’s operation and timely fix the problems, this will increase the unit’s operation time and will help operate the unit efficiently.

Maintaining the required pressure(EP21594)

The capability to maintain the constant pressure in the pressurized pipeline can expand the use of this machine in several areas (water supply systems arrangement, boosting water to low pressure, water supply systems, etc.).

This target can be achieved due to special design features.

There is an elastic tank for the fluid within the receiver (11). Pressure in the receiver is as high as 4 bar. The elastic walls of the rubber tank are under the influence of air pressure.

When the motor is switched on the pump starts to discharge the fluid into the rubber tank, thus filling it gradually. The air within the receiver (11) is compressed, and as soon as a certain pressure value is achieved (depending upon the factory preset value) the automatic switch (10) stops the pump motor.

The fluid in the tank is under pressure (produced by the air in the tank onto the walls of the elastic tank), which is required for the water supply system. When water discharge occurs in the water supply system (i.e. when some household devices are switched on, taps are opened, etc.), the pressure within the rubber tank will be reduced, as well as the pressure within the receiver (11). If the pressure drops by 1.4 bar, the automatic switch (10) will switch the pump motor on and the pump will start pumping water into the system until the automatic switch (10) is actuated (and the motor stopped).

This run is repeated, so that enables to maintain the required pressure in the water supply system.

While connecting the machine in the pressurized system consecutively, it shall be taken into account that the pressure within the system and the pressure produced by the machine are added. The total pressure value must not exceed 10bar.
