60 HZ Submersible Pumps

Shakti submersible water pump is in high demand due to its innovative mechanicaldesign and impeccable quality. It has carved a niche as the most predominant submersible pump andthe company is one of the leading suppliers of submersible pumps in India. It is available in allsize range starting from 100 mm. Shakti submersible pumps are manufactured from the superlativequality raw material using advanced fabrication technology,which ensure optimum performance and excellent quality.

Pump body is made with anti corrosive material with high wear resistance resulting in reductionin running costs and higher pumping efficiency and longevity. The pump can work continuously for a longer periodof time without any trouble. Higher reliability and best results even under harsh conditions make itacceptable to its users.

A wide range Pump

We offer submersible pumps with energy- efficient duty points ranging from 1m3/h to 280 /h. The pump range consists of many pump sizes and each pump size is available with an optional number of stages to match any duty point.

High Pump Efficiency

Often pump efficiency is a neglected factor compared to the price variations and are without importance of pump and motor efficiencies


When pumping 125 m3/h with a head of 200m for a period of 10 years $ 60,000 will be saved if pumps and motors having a 10% higher efficiency are chosen and the price is $ 0.10 per kW.


We offer a complete range of pumps and motors which as a standard are made completely of stainless steel AISI-304. This provides for good wear resistance and a reduced risk of corrosion when pumping ordinary cold water with a minor content of chloride.

Low Installation Costs

Stainless steel means low weight facilitating the handling of pumps and resulting in low equipment costs and reduced installation and service time. In addition pumps will be as new after service due to the high wear resistance of stainless steel

Bearing with sand Channels

All bearings are water- lubricated and have a square shape, enabling sand particles, if any, to leave the pump together with the pumped liquid.

Inlet Strainer

The inlet strainer prevents particles over a certain size from entering the pump.

Non-return Valve

All pumps are equipped with a reliable non-return valve in the valve casing preventing back flow in connection with pump stoppage.Furthermore , the short closing time of the non-return valve means that the risk of destructive water hammer is reduced to a minimum.The valve casing is designed for optimum hydraulic properties to minimize the pressure loss across the valve and, thus, contributes to the high efficiency of the pump.

Priming Screw

All QF and QF 30 pumps are fitted with a priming screw. Consequently, dry running is prevented because the priming screw will make sure that pump bearing are always lubricated.>Due to the semi-axial impellers of large QF pumps (except for QF 30) this priming is automatically provided.However, it applies to all pump types that if the water table is lowered to a level below the pump inlet neither pump nor motor will be protected against dry running.

Stop Ring

The stop ring prevents damage to the pump during transport and in case of up-thrust in connection with start-up.The stop ring, which is designed as a thrust bearing limits axial movements of the pump shaft.

Example: QF 125

The stationary part of the stop ring (A) is secured in the top bowl (Upper intermediate chamber). The rotating part (B) is fitted above the collet [split cone(c)].

Application :

The QF pumps are suitable for the following application :

  • Raw water supply.
  • Irrigation systems.
  • Groundwater lowering.
  • Pressure boosting.
  • Industrial applications.

Pumped Liquids

Clean, thin, non-aggressive liquids without solid particles or fibers

Operating conditions

  • Flow rate, Q: 1.2 m3/h – 280 m3/h
  • Head, H: Max 670m

The speed of the motors is approximately :

  • 4″ motors : n=2870 min-1
  • 6motors : n=2870 min-1
  • 8″ to 12″ motors : n=2870 min-1
  • The measurements were made with airless water at a temperature 2 of 20°c.The curves apply to a kinematic viscosity of 1mm /s. When pumping liquids with a density higher than that of water, motors with correspondingly higher outputs must be used.
  • The bold curves indicate the recommended performance range.
  • The performance curves are inclusive of possible losses such as non-return valve loss.
