Combination with vacuum pump

Enhanced Self-Priming Pump / Vacuum pump built-in type



Vacuum pump built-in type (UPM10-S, UPM10-N)

The main volute pump and the vacuum pump are installed on the same axis.

Colorless, odorless, harmless edible oil is used as circulating liquid in the vacuum pump.

Circulating liquid should be supplemented when it is under the marked level on the level gauge.

Install a check valve on the discharge pipe to prevent suction of air from the discharge side when the pump is first started. UPM10-0510S is equipped with a discharge ball valve (check valve) as a standard accessory, so the pump can be used by simply connecting hoses.


Enhanced Self-Priming Pump / Vacuum pump mounted/separate types

Vacuum pump mounted/separate types (UPS-N)

The vacuum pump is separated from the main volute pump (mounted type and separate type).

Ordinary water (city water and industrial water) can be used as circulating liquid in the vacuum pump (except S02 type).

Circulating liquid should be supplemented when it is under the marked level on the level gauge.

Fill with circulating liquid up to the level above the vacuum pump's axis when starting the pump for the first time.

Install a check valve on the discharge pipe to prevent suction of air from the discharge side when the pump is first started.

It is possible to change the capacity of the vacuum pump if the pumping liquid contains much air or the intake piping is long.

Circulating liquid may discharge from the supply tank. This is not a malfunction and is caused by any of the following reasons.

1.

Too much circulating liquid: Lower it to the level gauge position.

2.

Circulating liquid is removed by the air: The circulating liquid discharge amount will decrease as the exhaust air amount decreases.



Using this enhanced self-priming method, numerous kinds of transport equipment using suction pumping can be accomplished.
