The Pulsation Series E Plus offers manual control over stroke length and stroke rate as standard with the option to choose between 4-20mA and external pace inputs for automatic control. Twenty distinct models are available, having pressure capabilities to 300 psi (21 bar) @ 3 gpd (0.5 lph), and flow capacities to 600 gpd (94.6 lph) @ 30 psi (2 bar), with a turndown ratio of 100:1. Metering performance is reproducible to within ± 2% of maximum capacity.
 Over 25 years of excellence, PULSAtron pumps carry agency approvals of ETL, ETL Sanitation, CE and NSF 61 (PVDF material and PVC Degassing Head models).
