Internal Control Fixed Quantity Oil Supply Pump
Feature
1. A gear type volume pump that allows precise delivery across a wide range of viscosities.
2. It can be applied to long distances of more than 20m, and can also be used in small, large machine tools and high-precision machines.
3. To make full use of the fixed quantity oil supply system, the HMV series needs to be used for the valve.
4. It has an internal control, and therefore does not require separate control devices.
5. It has a built-in ullage decrease detector. (Float switch)

Operating Guide
1. The pump operates once power is connected and electricity is supplied. You can set the pause time using the Interval ① on the front of the pump, and discharge ② to set the operating time (seconds). Afterwards, the pump will repeatedly operate and pause
2. Minimum pause time of the pump is 3 minutes, and the minimum discharge time can be set to 3 seconds.
3. When operating the pump, the DIS, lamp ③ switches on, and during the pause, the INT lamp ④ switches on. When ullage inside the tank decreases, the EMG, lamp ⑤ switches on. When ullage inside the tank decreases, the EMG lamp ⑤ switches on.
4. The MAN. button ⑥ can be used for test operations and to let air out from the pipes (But, do not operate more than 5 minutes, as it can cause Motor damage)
5. The pump is set at 17kg/cm when released from the factory, but this may differ depending on the changes in the viscosities of the oils used (oil viscosity, surrounding temperature).
