External Control Fixed Quantity Oil Supply Pump
Feature
1. A highly reliable externally controlled fixed quantity oil supply pump.
2. It is used across a wide range of fields, and is especially suitable as a fixed quantity oil supply pump for high-precision, large machine tools.
3. The pump's main drive connection parts are made of single die casting pieces to ensure excellent durability.
4. An external control type that allows free pump control.
5. It has a built-in ullage decrease detector and a pressure decrease detector.

Operating Guide
1. It does not have a separate control device, and the pump operates automaticaly once power is connected and electricity is supplied.
The pause and operation times can be set in the same way as for HMGP-303.
2. Maximum operation time of the pump is 4 minutes, and the pause time needs to be set at 4 times the operation time.
※ Time needs to be followed for precise fixed quantity valve operation.
3. The manual button can be used for test operations and to tale out air from the pipes.
4. The pump is set at 17kg/cm2 when released from the factory, but this may differ depending on the changes in the viscosities of the oils used (oil viscosity, surrounding temperature).
5. The pressure switch can operate the pump and detect whether or not the set pressure has been reached within a given time, and send contact signals to the machine control device
during normal operation to check for errors.
