Next Generation Piston Pump Overview: 

  • Inlet and Outlet Flanges make it easier to plumb your system and eliminate leaks with flange fittings. (Add –F after model number).
  • Double piston rod seals work in unison to offer multiple stage protection between the wet end and crankcase.
  • Outboard cylinder plunger packing can be inspected or replaced in the field without removing the hoses.
  • Check Valves are designed for positive seal, easy priming and long life.
  • Single Valve Cap provides easy access to check valves without removing the hoses. Simple to service in the field.
  • Common or Independent Manifolds are available on the double pumps. Independent manifolds allow for dual flow divider usage or half-width application.
  • Main Shaft Seals incorporate a dual wiper that is enclosed in a grease cavity to flush out contamination. This helps to extend the life of the pump.
  • Direct Hydraulic Drive Piston Pumps are available along with standard Ground Drive (DRV) and Variable Rate Hydraulic Drive Kits (VRH).
  • Note: All standard Piston Pumps are cast iron and manufactured with Viton® Piston Packings and Buna O-rings and rod packing's. Most commonly used with liquid fertilizers that have pH greater than 5 and standard herbicides that are compatible with Buna and Viton®.
