The PULSAtron Series E Plus pump features an automatic control available with 4-20 mA DC direct or external pacing, with stop function. It also offers manual control by on-line adjustable stroke rate and stroke length. Series E Plus contains a highly reliable timing circuit as well as circuit protection against voltage and current upsets. This pump features solenoid protection by thermal overload with auto-reset. Nineteen distinct models are available, having pressure capabilities to 300 PSIG @ 3 GPD, and flow capacities to 504 GPD @ 20 PSIG, with a turndown ratio of 100:1. Metering performance is reproducible to within +/- 2% of maximum capacity.
As with Series E, our guided check valves, with their state-of-the-art seat and ball designs, provide precise seating and excellent priming and suction lift characteristics. Our timing circuit is highly reliable and, by design, virtually unaffected by temperature, EMI and other electrical disturbances. A variety of chemicals can be pumped by Series E Plus such as glass-filled polypropylene (GFPPL), PVC, styrene-acrylonitrile (SAN), Polyvinylidene Fluoride (PVDF), PTFE, Hypalon®, Viton®, ceramic, alloys and 316SS.
