The SILI CIS pump is a single stage, single suction, end-suction centrifugal marine pump. The CIS pump is designed according to international standard. ISO2858. It is for the end-suction centrifugal pump about the designation, nominal duty point and dimensions. The CIS horizontal centrifugal marine pump is suitable liquid for fresh water or sea water with little particle below 70 C degree. Specially mechanical seal for 120 C degree is available. CIS pump application for cooling pumps and fresh water booster or circulation pumps. In addition, bilge and ballast pumps, fire-fighting, general service pumps, Deck-wash pumps and so on. CIS pump spare parts can be also available in our sides.

CIS horizontal centrifugal marine pump Feather:

a. Designed to comply with ISO 2858 standard.

b. Back pull-out design. The bolting to the base plate through the casing feet together with spacer coupling; allow an easy disassembly of the rotating parts without disturbing the alignment and without disconnecting pipes and motor.

c. High quality mechanical seals(carbon/ceramic/stainless steel) with balanced configuration. Most of the pumps are designed with sealing rings at the front and back of impellers.(Gland packing is available).

d. Two bearing housings fitted with deep groove rolling ball bearings. Pumps are fitted with greased for life bearings, or bearings are oil bath lubricated.

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

f. Bare shaft and frame mounted for direct coupling to electric motors, coupled to 2 or 4 pole quality IEC motor configurations. It is with high level class and insulation, in both 50Hz or 60Hz, suitable for marine purpose.
