Electric Pumps

  • Highly Reliable - Two proven designs offering "order-of-magnitude" reliability improvement.
  • Industrial Strength - Suitable for extremely harsh conditions such as offshore oil/gas production, explosion-proof environments, and general industrial applications.
  • Chemically Resistant - Materials like 316L SS, Hastelloy™, ceramic, and Nitronic™ standard throughout, with wide range of seal choices. Materials in both pump series are compatible with H2S to NACE MR0175/ISO 15156.
  • Lubricated Drives - All CheckPoint drives are continuously bathed in oil, protecting mechanisms against dirt and ensuring full lubrication and maximum drive life.


 

 
MD SERIES A-F, Z
Diaphragm pumps with high particle tolerance and low pulsation.
  • Flow Rate - 0.01 to 2,220 USG/H (0.04 to 8,403 L/H)
  • Pressure - 0 to 2,500 PSIG (172 BARG)
  • Head - Diaphragm
  • Drive - Wobble-plate or crankshaft
  • Flow Rate Adjustment - Variable frequency drive (VFD) or bypass valve
  • Zero leakage - Diaphragms positively separate chemical from the environment and from the drive, ensuring zero leakage and high particle tolerance.
  • Nearly pulse-free flow - Sequentially-actuated compartments deliver continuous injection at up to 90 discharge cycles per second.
E & F SERIES
API 675 plunger pumps with high accuracy and head multiplexing capability.
  • Flow Rate - 0.01 to 22 USG/H (0.04 to 83 L/H)
  • Pressure - 0 to 9,000 PSIG (620 BARG)
  • Head - Plunger
  • Drive - API 675 compliant variable eccentric drive for "on-the-fly" stroke length adjustment.
  • Flow Rate Adjustment - Variable eccentric stroke length reduction
  • Chemical head reliability - Head design identical to and interchangeable with CheckPoint Series 1250/1500.
  • Multiplex capable - Reduction drives can be coupled in series, allowing independent adjustability using single motor.
