Burks UPA90 UPA120 Small Shielded Mute Household Booster Pump

Product Range

Power supply 1×230 V, 50 Hz; maximum operating pressure 10 bar; liquid temperature -10 °C to +110 °C; pump types: UPA90, UPA120.

Model Designation

The model consists of the series code, the size and the material code: UPA = Booster pump series; 90/120 = model size; P/B/S = pump housing material: plastic / all-bronze / stainless steel.

Construction

The UPA Booster pump is of the canned-rotor type: the pump and motor form one unit with no shaft seal, only two gaskets; the bearings are lubricated by the pumped liquid. Features: ceramic shaft and radial bearings; carbon thrust bearing; stainless steel rotor can and bearing plate; impeller made of corrosion-resistant material; pump housing made of cast iron, bronze, plastic, stainless steel, etc.

Materials

Installation

The pump must be installed with the motor shaft horizontal; before start-up, remove the plug screw on top of the motor to vent air; within a very short time the rotor forces the remaining air out through the shaft.

Motor

The UPA120 pump has three speeds: high, medium and low. The terminal box is easy to use and has cable terminals for various functions; the cable entry is sealed and has a built-in cable clamp; the cable entry of the single-phase motor can be pushed out from its lead-in for correct cable connection.

Applications

The UPA Booster pump is suitable for single-storey houses of less than 120 m², for boosting at gas boiler inlets, taps, showers and other domestic water outlets; it is especially suitable for houses supplied from a roof water tank.

Pumped Liquids

Depending on the liquid type, the Booster pump is designed for the following liquids: thin, non-corrosive and non-explosive liquids without solid particles or fibres; cooling water without mineral oil; domestic hot water; softened water. The kinematic viscosity of water at 20 °C is 1 cSt (1 mm²/s); if the circulator is used with higher-viscosity liquids, its hydraulic performance decreases — for example, 50% ethylene glycol at 20 °C has a viscosity of about 10 cSt, and the pump performance decreases by about 15%.

Maximum System Pressure

PN 10: 1.0 MPa (10 bar).

Curve Conditions

1. The bold part of the curves indicates the recommended performance range.
2. Test liquid: water without air.
3. The burks UPA pump curves apply to water with a density of ρ=983.2 kg/m³ at 20 °C.
4. All curves represent average values and must not be used as guaranteed curves; if minimum performance is required, it must be tested separately.
5. The burks UPA pump curves apply to a kinematic viscosity of v=1 mm²/s (1 cSt).
6. The conversion between head H [m] and pressure P [kPa] is based on water with a density of 1000 kg/m³; for liquids of other densities, such as hot water, the outlet pressure is proportional to the density.

Troubleshooting

1. The pump cannot start
a) The switch is in the OFF position → Set the switch to the operating position
b) Power supply fault → Contact the power supply department or check the household circuits
c) The pump shaft is seized → Remove the vent plug and insert a screwdriver into the slot at the top of the pump shaft and turn it
d) The flow switch is dirty → Clean the flow switch parts

2. The pump runs but produces no pressure
a) The main valve is closed → Open the main valve
b) Air in the system → Let the pump run continuously for a few minutes with a tap open and vent the air
c) The pump is dirty and the flow switch is blocked by impurities → Dismantle and clean the pump

3. The pump produces noise
a) Air in the system or the pump → Let the pump run continuously for a few minutes with a tap open, and open the vent screw to release the air

4. The pump does not stop after the tap is turned off
a) The flow switch is dirty → Clean the flow switch parts

If the fault cannot be cleared by the above methods, please call the local dealer or service provider immediately.

Notes

1. Read this installation and operating manual carefully before installation and use.
2. Pay attention to the safety warnings and explanations in this manual: danger from general causes — violation will cause pump failure or personal injury; danger from electrical causes — violation will cause pump failure or personal injury.
3. Failure to observe the safety warnings may cause personal injury, pump damage and other property loss, for which the factory bears no responsibility and no compensation.
4. Installers and operators must observe local safety regulations.
5. This product must be installed and maintained by professional personnel.
6. The user must ensure that the product is installed and maintained by personnel who are familiar with this manual and hold professional qualifications.
7. Do not install the pump in a damp place or a place where it may be splashed with water.
8. Install the pump in a place with drainage facilities (such as a floor drain) to prevent water accumulation if the pump leaks.
9. Never start the pump without pumped liquid.
10. Disconnect the pump power supply during installation and maintenance.
11. Do not frequently replenish the heating pipeline with non-softened water, to avoid increased calcium content in the circulating water in the pipeline, which may block the impeller.
12. In winter, if the pump system is not running or the ambient temperature is below 0 °C, drain the liquid in the pipeline system to prevent the pump body from frost cracking.
13. In summer or at high ambient temperatures, ensure ventilation to prevent electrical faults caused by condensation.
14. The pumped liquid may be hot and under high pressure; before moving or dismantling the pump, drain the liquid in the system or close the stop valves on both sides of the pump to avoid scalds.
15. If the vent bolt is removed, hot liquid under high pressure will flow out; make sure the escaping liquid causes no personal injury or damage to other parts.
16. If the flexible power cable is damaged, it must be replaced by professional personnel.
17. If the pump will not be used for a long time, close the inlet pipe valve and disconnect the pump power supply.
18. If the motor becomes hot or abnormal, immediately close the inlet pipe valve, disconnect the pump power supply, and contact the dealer or service centre at once.
19. If a pump fault cannot be cleared following this manual, immediately close the inlet pipe valve, disconnect the pump power supply, and contact the dealer or service centre at once.
20. Keep this product out of the reach of children; after installation, take isolation measures to prevent children from touching it.
21. Store this product in a dry, ventilated and cool place at room temperature.
