Sta-Rite MS Series Vertical Deep Well Jet Pumps Buyers Guide & Review

The Sta-Rite MS series vertical jet pumps are the industry standard deep well jet pumps for over-the-well “bolt-on” installations. The MS series jet pumps include the pre-plumbed external automatic regulator, pressure gauge, and pressure switch. Built for water systems and sprinkling systems in homes, farms and cottages.

A complete line of casing adapters to drive the 4″ double pipe or 2″ and 3″ single pipe jet packages are available. A jet package should be ordered with every MS series pump. All installations require an appropriate size adapter flange or casing adapter if bolt-on feature is desired.

Features:

  • Automatic pressure regulator: has a faster acting and quieter, design eliminating “hunting” for correct drive pressure. New, improved stem and guide are precisely molded to assure efficient, trouble-free performance on all deep wells
  • Quality, precision machined, close-grained cast iron pump body and base are specially treated to resist corrosion
  • Noryl impellers are precision-molded for perfect balance, and ultra-smooth for highest performance and efficiency
  • Pressure switch is high quality. Differential and cut-in/cut-out pressure settings are adjustable
  • Motor windings have superior insulation materials protect against excessive moisture and contaminants to ensure prolonged motor life
  • Mechanical shaft seal has precision-lapped and highly polished carbon-ceramic, stainless steel construction. Internal design guarantees continuous water lubrication for maximum protection
  • All electrical components are protected from dirt, dust and insects by a dustproof canopy. Ventilating air cannot contaminate vital switching components. This eliminates the most common cause of motor failure
  • Dynamically balanced rotor is diecast under high pressures for uniform performance and greater efficiency
  • Heavy-duty ball bearings are permanently lubricated sealed bearings, extensively tested to ensure extended life and smooth, quiet operation
  • Pump and motor shaft is stainless steel for maximum corrosion resistance. One-piece threaded shaft for positive impeller drive and alignment
