TFC Group APUMPHE Tower Smart Band A Circulating Pump

General

1. The APUMPHE circulation pump is designed for use in domestic heating and hot water systems. The product is most applicable to the following systems;

   • Stable and variable-flow heat supply systems
   • Variable-temperature pipeline heat supply system
   • Heat supply system with night mode
   • HVAC system
   • Industrial circulation system
   • Domestic heating and domestic water supply system
     This pump Is equipped with a permanent magnet motor and different hall pressure controller, capable or automatically & continuously adjusting motor performance to meet the actual needs of the system. The pump is equipped with a control panel on the front for easy operation by users.

2. Advantages

Easy installation and start-up
Provided with self adaptive mode AUTO (Initial setting). In most cases, the motor pump needs no adjustment and can be readily started and will adjust automatically to meet the actual needs of the systems.

High-degree comfort
Low operational noise of motor pump and whole system.

Operating Conditions

1. Ambient temperature: 0°C to + 40°C

2. Relive humidity (RH) Maximum humidity: 95%

3. Medium (liquid delivery) temperature Liquid delivery temperature: +2°C to +110°C
   To avoid condensation in control box and the stator, the temperature of liquid pumped by the motor pump must always be higher than the ambient temperature.

4. System Pressure
   Maximum system pressure: 1.0MPa (10bar)

5. Degree of Protection
   IP44

6. Inlet Pressure
   Liquid Temperature <85°C 90°C 110°C| | |
   ---|---|---|---
   Inlet Pressure| 0.05bar| 0.28bar| 1bar
   0.5m head| 2.8m head| 10m head

7. Pumping Liquid
   The pumping liquid includes thin, clean, non-corrosive and non-explosive liquid which shall not contain any solid particles, fiber or mineral oil, and the pump must definitely note be used to pump inflammable liquid such as rapeseed oil and gasoline. If the pump is used in a place with relatively high viscosity, the pump has lower performance. So when choosing a pump, the viscosity of liquid must be taken into account.

Installation

When installing APUMPHE series circulation pump, the arrow on the motor pump case indicates the flow director of liquid through the pump.
When installing the motor pump in the pipeline, the two gaskets supplied must be installed at the inlet and outlet.
During the installation, the motor pump shanti must be horizontal.

Position of Junction Box

Changing Position of Junction Box
The junction box can be rotated in a step of 90°.

The procedures for changing the position of junction box are as follows;

1. Close the valves at the inlet and outlet and release the pressure.
2. Unscrew and remove the four socket head screws that fasten the pump body.
3. Rotate the motor to the required position and align the four screw holes.
4. Install the four socket head screws again and fasten them clockwise making sure they are fully tightened.
5. Open the valves at the inlet and outlet.

Warning
Pumping liquid may be high-temperature and high-pressure; therefore, the liquid in the system must be completely drained the valves on both sides of motor pump must be closed before removing the socket head screws.

Thermal Insulation of Motor Pump Body

Note
Limiting the heat loss of motor pump body and pipeline.
Motor pump body and pipeline should be thermally insulated to reduce their heat loss.

Caution
Do not insulate or cover the junction box and control panel.

Electrical Connection

Electrical connecting and protection shall comply with local codes and norms.

Warning
The motor pump must be earthed.
The motor pump must be connected to an external power switch, with 3mm minimum contact gap in both poles.

• APUMPHE series circulation motor pump needs no protection from external motor.
• Check if the supply voltage and frequency are the same as parameters indicated on the nameplate of the motor pump.
• Connect the motor pump and power supply with the plug supplied together with the pump.
• Artier the power is supplied, the indicator lamp on the control panel is ON.

Control Panel

Controls on Control Panel

Indication Lamp Area of Motor Pump Setting

APUMPHE series circulation motor pump has three settings which can be chosen with the button. The motor pump settings are indicated with three different indication lamp areas.

Button for selecting motor pump settings
By pressing the button once at 2 seconds interval, the motor pump setting mode will change to the next sequence.
A cycle is constituted of every three presses on the button.

Motor Pump Setting

Motor pump setting based on System Type
Initial setting = AUTO (Self-adaptive mode) Recommended and available pump setting

• AUTO (Self Adaptive mode) can adjust the performance of motor pump based on the actual head demand of the system. Self adaptive mode adjusts over me to find the most effective setting, so before changing the motor pump setting, maintain AUTO (Self adaptive mode) setting for at least one week.
• If you select to change back to AUTO mode, the APUMPHE motor pump can memories its last setting in AUTO mode and continue adjusting the performance automatically.
• It may take several minutes or even hours to reach the optimal operation mode artier motor pump setting is changed from the optimal setting (the “Recommended above mention”) to one of the other optional setting. If the optimal setting of motor pump fails to enable each room to obtain desired heat distribution then you should change the motor pump setting to other settings.
• Please refer to Section 7.1 for the relations between pump setting and performance curve.

Motor Pump Setting and Performance

Relations between Pump Setting and Performance

function will automatically control the pump performance within the specified scope;
Adjust pump performance based on system scale;
Adjust pump performance based on load variance within a period of time; Under the AUTO mode, the pump will be set to proportional pressure control
Max| Velocity Max| It runs on the constant curve in a constant velocity. In the velocity Max mode, the pump is set to work on the highest curve under all working conditions.
Min| Velocity Min| It runs on the constant curve in a constant velocity. In the velocity Min mode, the pump is set to work on the lowest curve under all working conditions.

Performance Curve

Guide on Performance Curve

• Every setting of the motor pump has corresponding performance curve (Q/H curve). However AUTO (Self Adaptive Mode) mode covers just one performance curve.
• The input power curve (P1 curve) belongs to every Q/H curve. Power curve represents the power consumption of motor pump in given Q/H curve with Waits the unit.
• P1 value corresponds to the readings taken from the monitor of motor pump.

Curve Conditions

The followings are applicable to the performance specified in the APUMPHE series manual:

• Test liquid: air-free water.
• Applicable density of curve p=983.2 Kg/m³, and liquid temperature +60°C.
• All curves represent averaged value, and shall not be used as guarantee curve. If a specific performance is needed, then separate measuring shall be conducted.
• Velocity Max, Min curves have all been marked.
• The applicable Kinetic viscosity of the curve, u=0.474mm²/s (0.474CcST).
