The EK series of pumps are a horizontal triplex positive displacement design for use with 10-25 HP engines at flows over 17 G.P.M. and pressures to 40,000 P.S.I.
The EK series of pumps are a horizontal triplex positive displacement design for use with 10-25 HP engines at flows over 17 G.P.M. and pressures to 40,000 P.S.I. EK plunger pumps have valve-in-line, sectionalized stainless steel fluid cylinders, solid ceramic or proprietary solid carbide plungers, stainless steel valves and seats with self-adjusting V-rings packing of advance polymer material. EK plunger and packing sets are dripless closed loop, pressure water lubricated.

The EK power end is positive splash oil lubricated and is equipped with a sight glass for oil level check. Main roller and replaceable shell bearings connect the crankshaft and connecting rods to the stroking crosshead and ceramic plungers. One example of the versatility of the EK series pump is an electric powered, skid mounted model EK20EF unit. It can deliver 11.5 G.P.M. at 5,000 P.S.I. or by simply changing plungers and packing, 1.7 G.P.M. at 20,000 P.S.I.

Fluid End

  • Fluid Cylinders: Stainless steel is standard, other materials available to suit applications.
  • Valves and Seats: Heat treated stainless steel In-Line Valve System. All Valves may be reconditioned by surface grinding.
  • Plungers: Non-scoring, ceramic, optional colmonoy or proprietary solid carbide.
  • Packing: Self adjusting V-rings of advanced polymer material for up to 20,000 PSI and new low load (patent pending) one piece assembly for up to 45,000 PSI.
  • Lubrication: Plungers and packings are pressure lubricated by fluid from suction manifolds. Optional oil or alternative lubrication is available.
  • Manifolds: Combined light weight suction and discharge manifold is easily removable for simple maintenance. Different materials available to suit applications.

Power End

  • Power Frame: Rugged, high strength grey iron alloy casting.
  • Crankshaft: Double projection for access to either side of pump. Gas-nitride, hardened and tempered alloy steel.
  • Crankshaft Bearings: Interchangeable, heavy duty roller bearings.
  • Crossheads: Cylindrical type high strength alloy castings. Crosshead wristpins are hardened and ground steel.
  • Lubrication: Power end parts are splash lubricated by oil in crankcase reservoir. Oil return channels in power frame permit constant circulation and help keep it cool.
  • Connecting Rods: In special antifriccion bronze.
