Specifications

Single-stage horizontal, radially split volute casing pumps with feet below and single-entry radial impeller

Single-stage horizontal, radially split volute casing pumps with feet below and single-entry  radial impeller, end suction branch, radially upwards discharge branch.

Depending on operating conditions hydraulic balance provided by front or rear wear rings and balance holes. Casing cover with cooling or heating connections , shaft sealing by packings or mechanical seals of any design (single or double working ), connections for cooling, flushing or sealing liquid. 

Standardize pipework according to API plants

Flange possible according to GB, DIN, or ANSI

 

 

Size: 1-16 inches

Capacity: 0-2600 m3/h

Head: 0-240m

Temperature: -80-300 °C

Material: Cast steel, SS304, SS316, SS316Ti, SS316L, CD4MCu, Titanium, Titanium Alloy, Hastelloy Alloy

Advantage:

1.Design and maintenance standard complying with process industry is ensured. Rapid disassembly or assembly. Disassembly without removal of pipework and driver.

2.Only 7 bearing frames for 48 sizes. Same hydraulics(impellers) and bearing frames as for light or medium duty series CHZ

3.Low branch velocity, low noise level, due to additional primary measures at impeller, long rated life of casings.

4.Casing joint cannot break.

5.Optimum compliance with various operating conditions, closed  impeller with high efficiency, low NPSHR.

6.When casing and impeller wear rings and shaft seal are subject to wear, casing, impeller and shaft can be reused small wear of casing and impeller wear rings due to absence of solids.

7.Stable, aligning shaft position, robust shaft with small shaft deflection, few components ,few bearing checks required ,no cooling water pipework.

No cooling water consumption ,no increased bearing heating,

8.Wear-resistant bearing sealing

9.Possibility of replacing packings or mechanical seals of any design.

Economic consideration

1.High reliability and interchangeability .Short shut-down. Low maintenance cost

2.Few components, economic spare .part stock keeping, low stock keeping costs.

3.Long rated life of antifriction bearings, long rated life of shaft seals, short time for shutting- down, low maintenance costs higher efficiency, low operating

4.costs, low costs for pipework support and sound protection, low spare part and repair costs, high reliability. High reliability of pumps, low maintenance periods, low energy costs due to careful pump selection.

5.Small investment costs for plants .Considerable saving of repair and spare

6.part stock keeping costs, short repair periods .Long rated life of packing or mechanicals seals .Short shut downs .Easy maintenance, low operating costs No investment costs for cooling system .

7.High interchangeability, low modification costs .(no machining of stuffing box housing).
