Applications
PowerStar 4 pump P4
1.Hydrostatic testing of pressure vessels using various liquids (avoid running the pump dry or sudden release of outlet pressure);
2.Low volume, high pressure testing;
3.Low volume, liquid transfer (higher pressure capability than double diaphragm pumps).
1.A patented design;
2.One common air motor module for all eight ratios;
3.Easy conversion to separated (non-contaminating) configuration;
4.A double-ended unit that provides even higher flows;
5.Safe operation in hazardous environments;
6.Automatic shut-off at set pressure;
7.Stainless steel wetted parts.
