Air-Driven Hydraulic Pump / Oil Injector THAP E Series

Specifications

How to choose Hydraulic pumps

Points to check when selecting, with the values for this product (Air-Driven Hydraulic Pump / Oil Injector THAP E Series).

1. 1. Meet the pressure required for the job

   This product: Maximum Working Pressure 30 / 150 / 300 / 400 MPa

   Confirm that the pump's pressure is sufficient for the pushing force of a hydraulic nut or the pressure needed to lift a part with oil injection. The listed products range from 30 to 300 MPa. The 50 MPa and 100 MPa classes are mainly for hydraulic nuts, and the 150 to 300 MPa classes are mainly for railway wheels and large press-fit parts. Also make sure the allowable pressure of the connected equipment is not exceeded.

2. 2. Match tank capacity to the oil volume of the load

   Large hydraulic nuts and the hydraulic chambers of fittings need a large amount of oil to fill. If the tank is small, oil must be replenished partway through the job. The listed products vary from a few cm3 to 2700 cm3, so select based on the oil volume required by the connected equipment.

3. 3. Estimate working time from the delivery volume per stroke

   The larger the delivery volume per stroke, the fewer strokes are needed to fill the oil, so large-volume loads can be completed faster. In the high-pressure range, however, a smaller delivery volume per stroke makes the operating force lighter. Two-stage pumps can switch between both modes, which makes them advantageous for applications that need high volume and high pressure.

4. 4. Choose the drive method based on the scale of work

   Manual pumps are highly portable and can be used at sites without power or compressed air. For work on large fittings or propellers, which need a large oil volume and continuous supply, air-driven pumps reduce operator effort. For air-driven pumps, also check that the air pressure available at the site matches the specifications.

5. 5. Match the connection thread and hose to the equipment

   This product: Discharge port thread G3/4

   If the discharge port's thread standard does not match the hydraulic nut, injection nipple or hose, the connection will not work. Adding more adapter fittings can also cause leaks. Check that the length of the supplied high-pressure hose is enough to place the pump at a distance from the work position.

6. 6. Check how pressure is monitored

   Reading the pressure is essential for controlling pushing distance and press-fit operations. Models with a digital pressure gauge show the pressure as a numerical value. If a pressure gauge is included, confirm that its measuring range suits the maximum working pressure.
