E Series Information

Features & Benefits
Dual Manual Control: Stroke frequency and stroke length are manually adjustable. Pulsatron Series EChemical Metering Pump by Pulsafeeder • Manual Control by on-line adjustable stroke rate and stroke length. • Highly Reliable timing circuit. • Circuit Protection against voltage and current upsets. • Panel Mounted Fuse. • Solenoid Protection by thermal overload with auto-reset. • Water Resistant, for outdoor and indoor applications. • Indicator Lights, panel mounted. • Guided Ball Check Valve Systems, to reduce back flow and enhance outstanding priming characteristics. • Few Moving Parts and Wall Mountable. • Safe & Easy Priming with durable leak-free bleed valve assembly (standard). • Reliable metering performance. • Rated "hot" for continuous duty. • Leak-free, sealless, liquid end.
General Description
Pulsafeeder PULSAtron Series E chemical metering pumps are positive displacement, diaphragm type pumps. Output volume is adjustable while pumps are in operation from zero to maximum capacity. The PULSAtron Series E pump features manual control by on-line adjustable stroke rate and stroke length. It has been agency approved for demanding outdoor and indoor applications. Series E is internally dampened to reduce noise which makes it very acceptable for household installations. It is also water resistant to accommodate outdoor installations as well. It features guided ball check valve systems to reduce back flow and enhance outstanding priming characteristics. Series E also offers few moving parts and is easily wall mountable. Series E 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. Series E pumps continue to meet their specifications for pressure and capacity even during extended use. It also features safe and easy priming with durable leak-free bleed valve assembly.
Pump Controls
Adjustment is by means of readily accessible dial knobs, one for changing stroke length and the other for changing stroke frequency. Both knobs are located opposite the liquid handling end.
Drive Assembly
The pump drive is totally enclosed with no exposed moving parts. Electronics are housed in chemical resistant enclosure at the rear of the pump for maximum protection against chemical spillage. Average electrical power consumption is 130 Watts.
Materials of Construction
Chemical metering pump housing shall be of chemically resistant PBT thermoplastic. All exposed fasteners are stainless steel. Valve seat and seal ring are renewable by replacing the cartridge valve assembly.

Engineering Data - Tech
Reproducibility: +/- 2% at maximum capacity Viscosity Max CPS: For viscosity up to 3000 CPS, select connection size 3, 4, B or C with 316SS ball material. Flow rate will determine connection/ball size. Greater than 3000 CPS require spring loaded ball checks. See Selection Guide for proper connection.
