The Berkeley MS series well pumps with motors are built for residential, industrial, commercial, multiple housing and farm use water transfer applications. Each MS pump is MGS stainless steel, engineered with precision and high-quality to deliver efficient and dependable performance even in rough, aggressive water. These pumps are built to deliver long-term, trouble-free service.  Its floating impeller design resists sand and reduces sand locking. These pumps feature the SignaSeal staging system. Features: Package includes motor and pump Staging system incorporates a harder-than-sand ceramic wear surface that when incorporated with the floating impeller design, greatly reduces problems with abrasives, sand lock-up and running dry 300 grade stainless steel discharge is corrosion-resistant for durability in aggressive water Large octagon wrench area for ease of installation Exclusive self-lubricating Nylatron discharge bearing resists wear from sand Corrosion-resistant 300 grade stainless steel intake for durability in aggressive water Positive drive from 7/16 in. hexagonal heavy-duty 300 grade stainless steel shaft Stainless steel coupling press fit to pump shaft.

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.
