CHEM-GARD PG
Thermoplastic PRIME-GARD® Self-Priming Pumps
This heavy-duty, self-priming, centrifugal pump handles flows to 40m3/hr (175 gpm), making it ideal for acid buggies, sump and tank evacuation, and emergency overload pumping. It is often specified for in-line pump service where headroom prevents the use of vertical pumps, and other applications where self-priming from depths to 4.6 metres (15 ft), may be required. These pumps are available in the full line of homogeneous thermoplastics, and the pedestals are inter-changeable with all standard CHEM-GARD models.
General
