Compared to the conventional products, the pump efficiency increased by 35%. This type became smaller, lighter, 5-dB quieter and 50% reduction in vibration.
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.
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.
Its innovative self-priming design does not cause the maximum self-priming height to be reduced by liquid temperature.
●Seawater circulation and chemical solution circulation (some excluded)
●Coolant circulation, fish preserves and seawater plants
●Hydroponic culture and plant factories
※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.
| Fluid | Criterion |
|---|---|
| Sodium hypochlorite | Up to 5 ppm of concentration |
| Caustic soda | Up to 5% of concentration |
| Hydrochloric acid | Up to 30% of concentration |
| Sulfuric acid | Up to 10% of concentration |
| Citric acid | Up to 10% of concentration |
※The above corrosion resistance table shows the standards when a fluid temperature is normal(0 ～40 ℃).
