Pumps for Hydrostatic & Hydrodynamic Tests

Electric Test Pump type EP601D/200

Electric test pump by  URACA Pumpenfabrik consists of the following components:

1. High pressure reciprocating 3 plunger pump

Working pressure: max. 200 bar.
Flow rate max: 5  l/min

2. Glycerin-filled gauge - blade diameter 63 mm
3. The overflow valve with setting knob - limits the maximum operating pressure of the pump (works as a safety valve) and allows you to increase the operating pressure during the pressure test.
4. The back-pressure valve - keeps the pressure test after the engine is off.
5. Release valve - allows decompression and drain the water from the test object after completion of the test.
6. Vent valve - allows venting the pump before the beginning of the trial.
7. The electric drive:  3-phase 2.2 kW - 400 V, 50 Hz 1450 min-1.
8. Transmission - flexible coupling with cover.
9. An engine stop switch with 3 m long cable and  a plug.
10. The buffer tank with float valve, with capacity of 10 l.  and a water supply connection.
11. The device is mounted on a rigid frame.

Total weight: 37 kg (W/100),   44 kg (D/200).
Dimensions (L x W x H ): Approx. 730 x 380 x 350 mm.

Standard equipment:

  •    high-pressure hose , 3 m long with connector with external thread G1 / 2 ''
  •    the supply/discharge hose /  DN13,  5 m long

How it works:

The pump draws liquid from the surge tank. On stand the tank is connected to the water supply through the hose and appropriate adapters. The built-in float valve closes the water inlet when the tank is full at the maximum level.

An overflow valve pressure can be continuously adjusted from approx. 20 bar/ 2 MPa up to the maximum value. Once the required test pressure is reached, the pump  should be immediately turned off. The pumped liquid in a closed cycled, heats up quickly and can cause damage to the high pressure pump and burns personnel.

The drain valve is closed during the test. After the procedure, it is opened , causing decompression of the system. The liquid flows through the valve to the floor, but you can extend the drain hose and bring it down the drain or a suitable tank.

NOTE: The offered pumps are not designed for continuous operation!

Proper work during a typical pressure test  should run  as follows:

  1. the pump pumps the liquid under pressure for 5 minutes ("boosting" the pressure in the test object)
  2. the pump is not running for 10 minutes.
  3. the  pump again pumps for 5 minutes, and so on.
