Specifications

1,Single-stage single-suction 
2,Axial suction centrifugal pump 
3,Back-pull-out design

Min inlet pressure

Min inlet pressure depends on NPSH +0.5m safety margin + gasified pressure. It should be re-calculated the inlet pressure if one of the following happens.

*The liquid is more warm.

*The flow exceeds the nominate value.

*Suction distnace is very long or inlet pipe is very long.

*System pressure is too little.

*Inlet pressure is low.

 

Typical application

*Clean, thin, non-corrosive, non-flammable or non-explosive liquid without grain or fiber.

*Water supply system

*Heat, air condition system

*Irrigating, farming

*Booster, constant pressure water supply

*Industry cooling, heater circulation system

*Firefighting, splitting system

*Industry transferring, drainage system

 

Construction

*Non-self-priming, single stage, single suction, horizontal, axial suction and radical discharge, pump body is fixed by base.

*Use bering cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part.

*Compacted shaft, use deep grove grease lubricated roller bearing.

*Connect pump and motro with semi-flexible coupling.

*Use standard wearable mechanical seal.

*TEFC motor, size complies to IEC standard, installation type B3.

*The dimensions is conform to ISO 2858

 

Specificaton

*Flow: Max 520m3/h

*Power:Max 160Kw

*Head: Max 160m

*Liquid temperature: -15°C - 110°C

*Working pressure: Max 16bar

*Inlet and Outlet diameter: Inlet diameter: DN50-DN200; Outlet diameter: DN32-DN150

 

Curve conditions

*Curves tolerance is according to ISO9906, Annex A;

*All curves are based on the measured value of constant motor speed 2900rpm, 2950rpm, 1450rpm or 1480rpm.

*The measurements were made with airless water at temperature of 20°C. The curves apply to a kinematic vis-cosity of 1 mm2/s (1 cst)

 

Features

*Back-pull-out design, without having to disurb pump body and pipelines when servicing.

*All the models only use 4 kinds of pump shafts and bearing cover, make parts exchangeable.

*Impeller is optimum design, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise.

*Casing and casing cover use wearing neck ring structure, which makes pump easy to maintain, makes parts work longer. The replaceable seal ring, makes pump work efficiently in a long time.

Q:What are the ways of hydraulic pumps?
Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element.
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Unreasonable, easy to produce throttling loss, pressure loss, pressure reduction, easy to cause cavitation
Q:How can the submersible pump level meter be connected?
Installation of submersible pumps dedicated liquid level float, connected to the submersible pump power line (some submersible pumps bought with), or received submersible pump control circuit, high starting, low stop.
Q:Why should the pump be closed when the centrifugal pump is started?
Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.
Q:Is the diaphragm pump and the drain pump one?
Generally composed of actuators and valves.Pneumatic diaphragm pump, which has four kinds of materials: plastic, aluminum alloy, cast iron, stainless steel. The electric diaphragm pump has four kinds of materials: plastic, aluminum alloy, cast iron and stainless steel. Diaphragm pump diaphragm according to different liquid media, respectively, NBR, chloroprene rubber, fluorine rubber, PTFE, poly 46 ethylene to meet the needs. Placed in a variety of special occasions, for pumping various media.
Q:How about the depreciation of vacuum pumps?
(a) housing and buildings for 20 years;(two) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;
Q:What are the application areas of pumps?
Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:
Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
Q:5 floor water pressure is too low, what kind of water pump is better?
The location of the pump is too far away from the pumping pool, the suction of the pump is not enough, cavitation phenomenon, pumping water, this water pump manufacturers, the pump will be placed in a reasonable position
Q:What does "anti pump" mean in pump operation?
The pump again is the pump, the theory is the plugging problem can be solved, but if you are against the pump after pump has been plugging serious, and pump has been unable to solve the plugging problem, finally the worst solution is a split pipe, if the situation under enormous pressure will only exacerbate the plugging
