Mini-Matic pumps are designed to provide greater convenience and efficiency to suit a range of demanding chemical applications in both Polypropylene and Kynar-wetted construction materials, with XL (Santropene), Geolast, or Teflon interiors. The E8 3/8 in. pump weighs only three pounds, yet it pumps up to 6.8 gallons per minute with pressures up to 100 psi. Pumps can be mounted upright, sideways, or inverted.
