Stroke frequency and stroke length are manually adjustable.

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.

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.

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.

See Specifications tab. 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.
