SD,SP series stainless steel submersible water pumps,oil filled pumps

SHUILISHI stainless steel submersible pump

Features and BenefitS

.It is the non-corrosive liquids that does not contain the thin clean solid particles or fibers.

.For containing oil or slightly contaminated liquids,SHUILISHI offers a range of stainless steel submersible pumps with strong corrosion resistance.

.All SD,SP series submersible pumpsare verticle or horizontal installation.

.For the SDB multipurpose submersible pump,installation can be vertical,inclined,horizontal and hanging.

.SHUILISHI company offers stainless steel series submersible pumps,and its effective work flow range is from 0.5m to 100m 3/h,and maximum head is up to 595m.

.The range of pump covers a variety of specifications and in each specification of the submersible pump you can choose different levels to match the working point in actual demands.

.The material of SP series submersible pump is complete with DINW,-Nr1.4031(AISI 304)stainless steel.Especially in the transport of cold water containing small amounts of chloride.

.All the rubber parts of SP series submersible pump are made of fluorine rubber.

.All SD,SP series submersible pumps are designed with standard size water filters,the main reason is to prevent debris or particles larger than a certain size into the pump.

.Each pump’s outlet is equipped with reliable non-return valve to prevent the liquid running back when the pump stops running .

.And the valve closing time is short,which will reduce the risk of damage due to water hammer.

.All sereis of submersible pumps valve bodies have good water performance design which can reduce the pressure loss throgh the valve and thus help to improve pump efficiency.

Pump curve condition

.Curve Tolerance in line with ISO2548 standards.

.Performance curve represents the performance of the standard motor under actual speed.

.Approximate speed of the motor

3inch        n≈2875r/min

3.5inch      n≈2875r/min

4inch        n≈2875r/min≈3450 r/min

5inch        n≈2875r/min≈3450 r/min

6inch        n≈2875r/min≈3450 r/min

8inch        n≈2875r/min≈3450 r/min

.All the measurments are conducted at 20°C water without gas.

.When the density of transport liquid in the pumpis larger than that of water,it must be matched with higher output power moto.

.The thick lines part indicate the range recommmended as the best performance .

.Q/H curves include the loss of the intake and valve in the actual speed.

.Eta represents the efficiency of pump.
