Directions for use

The 1PM type Pump is an air-driven pump that reciprocates the piston by air pressure, so a 3-way switching valve is required to turn the air on and off.
The 2PM pump is designed to generate a discharge pressure of 0.5MPa with an air input pressure of 0.1MPa (Pump ratio 1: 5). However, since the operating pressure of the metering valve is 1.2MPa or more, the air input pressure must be set to maintain 0.35 to 0.5MPa. Also, adjust the air input pressure not to be 0.45 MPa or less even if oil (liquid) jumps from the jet nozzle at the tip.
(3) The viscosity range of the oil (liquid) used is 10 mm2 / s to 100 mm2 / s (viscosity when used). If the viscosity is extremely high, it is yes that repeated discharge can not be performed in a short cycle (intermittent time).
Aluminum material (PumpBody) and NBR rubber material (O-ring) are used for 4PM type Pump. When using special oil (liquid), please contact our Global Center.

※ Do not disassemble the internal mechanism, as it will spring out more strongly by the spring. It may cause serious injury.
