Type TW 11400
Hydraulic pump for water

The high pressure Type TW hydraulic pump is specifically designed for water applications. Since water is the most demanding fluid, the Type TW pump can also be used with most other fluids including water-based solutions and oil-based fluids. Separation of the lubricating oil and the pumped fluid is achieved by the installation of a

cavity between the cylinder block and the case. Bypass from the pistons is collected in this cavity and returned to the inlet side of the pump. The pump is available with three pistons. Additional variations are possible by varying the input speed to a maximum of 1,800rpm (1,000 bar).

Pressure and flow combinations Pump No. No. of pistons and size (ins) Theoretical flow (cc/rev) Max pres. (bar) 11400 - 41 3 x 0.375 2.40 1,000 11400 - 42 3 x 0.437 3.25 850 11400 - 43 3 x 0.500 4.25 690

Material Stainless steel wetted parts; cast iron casing. Weight 40 Kg.

Installation Rotation is bi-directional and the pump may be mounted horizontally or vertically. If vertical mounting is selected, our Technical Department should be consulted. A suction filter of at least 125 microns should be used, and care should be taken to ensure that the filter is of adequate size and does not cause more than 300 mm Hg depression.

Pipes should be of sufficient size to give not more than 3.70 m/sec velocity in the delivery line and 1.20 m/sec in the suction line. The suction line should be kept under positive pressure when the pump is stationary to allow priming. We recommend that the fluid reservoir should be between 50 mm and 3 m above the suction port.
