The Berkeley MS series is a base mounted, vertical multi-stage deep well jet pump built for use in water systems and sprinkling in homes, farms, and cottages. Engineered with a rugged cast iron body, the MS series vertical jet pumps are the industry standard deep well jet pumps for over-the-well "bolt-on" installations.

These pumps include the pre-plumbed Berkeley external automatic regulator, pressure gauge, pressure switch, and a complete line of casing adapters to drive the 4" double pipe or 2" and 3" single pipe jet packages.

Features

  • Automatic pressure regulator with a faster acting and quieter design eliminates "hunting" for the correct drive pressure
  • New improved stem and guide are precisely molded to assure efficient, trouble-free performance on all deep wells
  • Quality built precision machined, close grained cast iron body and base are specially treated to resist corrosion
  • Precision molded Noryl impellers for perfect balance
  • Ultra-smooth for highest performance and efficiency
  • High quality pressure switch with adjustable differential and cut-in/cut-out pressure settings
  • Superior insulation materials protect motor against excessive moisture and contaminants to ensure prolonged motor life
  • Mechanical shaft seal has precision lapped and highly polished carbon-ceramic surfaces
  • Internal design guarantees continuous water lubrication for maximum protection
  • Dustproof motor cover protects all electrical components from dirt, dust, and insects
  • Ventilating air cannot contaminate vital switching components
  • Dynamically balanced rotor is die cast under high pressure for uniform performance and greater efficiency
  • Heavy-duty permanently lubricated ball bearings are extensively tested to ensure extended life and smooth, quiet operation
  • One-piece stainless steel threaded pump and motor shaft for positive impeller drive and alignment
