Openwell submersible pumps are replacing centrifugal pumps at a number of places because of some of the inherent advantages such as: No separate foundation is required. Cooling is much better & hence longer life. Convenient to move from place to place. Foot – Valve is not required. Suction head is eliminated. DESIGN - OPENWELL SUBMERSIBLE PUMPS No Foundation – No pump house required. Pump operates under water, hence no foot valve – no priming – no suction problems- less possibility of burn-out of motor. Long life due to, cast iron construction – water lubricated journal & thrust bearings – dynamically balanced all rotating parts – motor designed to withstand wide voltage fluctuation. For safety, earthing terminal is provided. Application Domestic, Garden, Irrigation, Drip & Sprinkler irrigation, Public water supply, Industrial & rural water supply. Special Features No suction & priming problems No need of pump house Noiseless operations Single shaft for pump and motor ensures permanent correct alignment Suction head is eliminated High operating efficiency Extremely hard wearing water lubricated bearing Highly durable water cooled rewindable motor Can be easily dismantled and repaired  

Locked impeller design for noise free Durability Low Power Consumption Rugged Construction  

Single or multistage centrifugal pumps in pump shroud or in ring section design. Radial or mixed flow hydraulic systems; Suction casing fitted between motor and pump with strainer to protect the pump from coarse particles / sand in the fluid. Pumps with check valve (non-return valve) in option are supplied. Available with threaded particularly suitable for vertical installation in narrow deep wells. Additional bearings are fitted depending on the number of stages. Stainless Steel inserts are fitted to the impeller. The impeller hub is protected by stainless Steel inserts are fitted depending on the number of stages. This design improves the starting torque & has the effect that solid particles such as sand are propelled outside. Application Irrigation, Domestic, Civil water supply, Fountains, Industrial, Rural water supply, Fire fighting, Pressure boosting units, Ponds, Gardens, Sprinkler systems and Mining.

SUBMERSIBLE PUMPSETS V6 & V8   6" Stainless steel series submersible pumps are made of corrosion resistance stainless steel with built in stainless steel check valve for years of trouble free service. All vital components are made of anti-corrosive high quality 304/316 grade stainless steel and the shaft in SS 431/329 and well designed for the best possible hydraulic efficiency. Pumps are multistage centrifugal type and the optimal design of impellers and diffusers enables the best possible hydraulic efficiency. The pump is firmly coupled to a submersible electrical motor which operates submerged beneath the surface of water. Built in check valve prevents back flow and reduces the risk of water hammering.
