Characteristics

●High performance and energy saving

Compared to the conventional products, the pump efficiency increased by 35%. This type became smaller, lighter, 5-dB quieter and 50% reduction in vibration.

●Long-life and no liquid leakage

There is no liquid leakage due to no shaft seal part. As made of resin, this type is appropriate for transporting highly corrosive special liquid.

●Freely detachable self-priming tank

A freely detachable self-priming tank design. Self-priming and non-self-priming can be selected according to application. Though it is easy to switch between a self-priming pump (PMDS type) and a non-self-priming pump (PMD type), contact us before switching.

●No reduction in max. self-priming height due to liquid temperature

Its innovative self-priming design does not cause the maximum self-priming height to be reduced by liquid temperature.

Application

●Seawater circulation and chemical solution circulation (some excluded)

●Coolant circulation, fish preserves and seawater plants

●Hydroponic culture and plant factories

Caution

※Chemical resistance
Chemical resistance must be verified before using the products by checking whether an intended purpose can be achieved with a preliminary test, etc.
※In order to use cold water, apply lagging materials and/or heat-insulating materials as measures against dew condensation if necessary.
