The SILI CLHB pump is an ideal centrifugal marine pump type, which is popularly used in marine and offshore industry. It is can be in spacer coupling type. It is a centrifugal type with volute casing, vertical construction, single stage, single flow, in line and same flanges. CLHB pump is suitable liquid for fresh water or sea water with little particle below 70 C degree, (specially mechanical seal for 120 C degree). CLHB pump application for fresh and seawater cooling pumps, bilge and ballast pumps, fire-fighting, general service pumps, deck-wash pumps and so on. CLHB pump spare parts can be also available in our sides.

CLHB vertical centrifugal marine pump Feather:

a. Curved blades to ensure low NPSH-values and high efficiency, close type, statically and dynamically auto balanced.

b. Shaft supported by radial and thrust ball bearings either greases or self-lubricated, independent bearing body and pump shaft support.

c. High quality replaceable mechanical shaft seal of an approved brand, tungsten carbon/ceramics, A special mechanical seal for temperature higher than 120 C.

d. Bronze pump casing&body, impellers and stainless steel shaft as standard for sea water.

e. Flanges are usually in Chinese GB standard, however other standard flanges in EN(DIN), ANSI, and JIS and so on, can be also provided.

f. Coupled to 2 or 4 pole quality IEC motor configurations, with high level class and insulation, in both 50Hz and 60Hz, suitable for marine purpose.

e. Spacer coupling type, available, when replacing both mechanical seal and impeller, it only needs to remove the elastic clutch and the nut on the lid and, without removing the motor, pump casing and pipeline(for the spacer coupling type only)

Refer to pump and its spare parts details from the CLHB pump catalogue, and contact us more information for pump specification, manual, performance curve, installation dimension, spare parts list and so on.

The CLHB pump, in spacer coupling type design. The pumps are available in sizes ranging from 25 mm to 250 mm on the inlet and outlet flange.The suction flange is same with the discharge flange.

The CLHB pump is a single stage, single suction centrifugal pump used in marine and off shore industry. The pump is a so-called in-line type, i.e. suction and pressure branches are mounted on the centre line.

Shaft and shaft seal: basically there are two kinds of shaft sealing: the packing and the mechanical seal, a mechanical shaft seal with stainless steel shaft is a standard.

Bearings: the pump shaft is guided by antifriction bearings. It is usually designed for grease lubrication(standard) or oil lubrication.

Material for wet part: pump impeller, pump cover & casing(body) are in brozne for standard for sea water, while for fresh water, cast iron pump casing is optional.

Motor: in high class and insulation level, TEFC, IEC standard, 50Hz or 60Hz, especially designed for marine and off shore purpose.

CLHB pump Technical details:

–Motor: 2 or 4 pole quality IEC motor configurations, with high level class(class F or higher) and insulation(insulation IP44 or higher), in both 50Hz or 60Hz, Y-H series, suitable for marine purpose, Starting in direct type(small power) or Star-delta type.

–Material: pump casing/cover: bronze(sea water) or cast iron(fresh water), pump impeller: bronze, shaft and key, stainless steel

–Shaft seal: mechanical seal, material: SIC(silicon carbide),hard alloy and ceramics, double face mechanical seal for big power pump.

–Coupling: Common flexible coupling type, material in carbon steel, or with an inter spacer coupling type.

–Bearing: motor side, two enclosed antifriction bearing, lubricated by grease; pump side, upper antifriction bearing, lower thrust bearing, lubricated by oil or grease.
