Toyooki HPP Japan Fengxing plunger pump HPP-VCF2V HPP-VCC2V HPP-VD2V HPP-VD2V-F31A3-EE-A HPP-VF2V HPP-VF2V-L63A3-A

The standard direction of rotation is clockwise, viewed from the
shaft end.
Run the drain pipe such that the drain port is located at the highest
position.
The permissible drain back pressure is 0.03 MPa max.
The suction pressure must be within −0.02 MPa.
Before starting the pump, supply hydraulic fluid through the oil filler
port so that the pump is filled with the hydraulic fluid (1 L).
When mounting a check valve at the pump outlet side, use a valve
with a cracking pressure of 0.005 MPa.
Always install a 150-mesh filter and strainer in the suction line.
Installation of a line filter of 10 to 20 µm is recommended in the
return line to the reservoir.
