Product Description:

Single Stage End Suction Chemical Pump

Description of Single Stage End Suction Chemical Pump

ASP5020 series standard chemical pump is a centrifugal pump, which includes horizontal, single stage, single suction, volute casing, foot-mounted, cantilever type.

The pump is designed based on the SO2858 "End-suction centrifugal pumps Designation,nominal duty point and dimensions", and GB5656 "Technical specifications for centrifugal pumps(Class II)".

The pump is reliable, steady and efficient in hydraulic performance, and comply with International standards with simple structure and easy maintenance.

Sealing system includes packing seal, single mechanical seal, double mechanical seal and tandem mechanical seal according to different working conditions.


Application Area of Single Stage End Suction Chemical Pump

Especially applied in: Refinery, Chemical and Petrol-chemical industry, Power plant, Sugar factory

Transmit liquid that is low temperature or high temperature; liquid that is neutral or corrosive; liquid that is clean or includes solid particles.


Performance Range of Single Stage End Suction Chemical Pump

Specification: DN 32~300mm

Capacity: Q 2~2000m³/h

Head: H ~160m

Work pressure: P ~2.5Mpa

Work temperature: t -80~+300ºC


Structural Characteristics of Single Stage End Suction Chemical Pump

Bearing support,shaft,sealing box and impeller form an installation module,which can be changed among different pumps in order to save the holding cost of spare parts.In the meantime,after dismantling separable coupling,there is no need to dismantle pipeline and motor before disassembling the installation module formed by Bearing support,shaft,sealing box and impeller.

(1) Pump casing

Single volute and double volute structure shall be designed on the pump casing,with interchangeable impeller ring on the pump casing to protect pump casing from abrasion.And pump casing shall also be designed with the structure of heating jacket.

(2) Flange position

Inlet flange is horizontally suctioned,outlet flange is radially upwards.

(3) Hydraulic and axial force balance

Performance curve is stable with low cavitation and high efficiency,and this characteristic shall be kept like this even when load is not enough.

(4) Bearing and lubrication

Single-row ball-bearing and thin oil lubrication shall be applied on the bearing;bearing sealing is labyrinth seal;oil level is automatically controlled by a constant oil cup.

(5) Shaft seal

Mechanical seal box or packing seal box shall be applied on the shaft seal,and seal box can be cooled or heat retaining,shaft seal can be cooled or washed.

(6) Flange pressure rating and rotation direction

Flange design pressure rating is PN16 and PN25,and ANSI125,150 is also applicable.

The pump rotates clockwise from the direction of motor end.

Q: How can I get trained on CNBM products?

A: Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

Q: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q: If I increase the power of the motor, must I also increase the power of the inverter?

A: You must select the size of converter that allows maximum absorption of the electric motor.
