Description

volute casing centrifugal pump :
 
ZTAH, ZTHH pump are cantilever, horizontal centrifugal slurry pump that are fit for metallurgy, mine, coal, electric power and building materials to transport slurry wit strong corrosion and high concentration. The pumps can be also used by multistage in series. The pump body has changeable antifriction metal liner or rubber liner, the impeller is made from antifriction metal or rubber. Pump body liner and impeller of RTHH are made from antifriction metal. Shaft glands of RTM, RTAH, RTHH pump can adopt packing seal or centrifugal seal. Position of disgorge opening in the pump can be spaced in *5°  angel, turn eight different angles for installation.
Details of centrifugal slurry pump:
Split outer cover plate and frame plate are made of ductile iron or grey iron, protect the wear liners and provide high operation pressure capabilities.
1. Long bearing life: The bearing assembly is with large diameter shaft and short overhang minimizes deflection and vibration. Heavy duty roller bearings are adopted with Lithium white Grease and housed in a removable bearing cartridge. No leakage, a little maintenance, convenient rotor adjustment.
2.Shaft sleeve let Shaft life longer: A hardened, heavy-duty corrosion-resistant shaft sleeve with ‘o’ ring seals at both ends protects the shaft.
3.Wear resistant and anti-abrasion wet parts: The wet parts can be made of hard metal (****5% Chrome alloy) or pressure molded rubber. More materials are also available.
4.Easily replaceable liners: Liners are bolted to the casing.
5.Simple maintenance throat-bush: the mating face of the throat bush is tapered, so the wear is reduced and removal is simple.
6.Easy adjustment of impeller: An impeller adjustment mechanism is provided below the bearing housing.
7.High efficiency and high head design are also available. The liners and impellers for high-head pumps are adoptable of hard metal only.
8.Centrifugal shaft seal, mechanical shaft seal and packing shaft seal are available.
9.Power source: 3phase,*0Hz or *0Hz
*0.Medium temperature should not exceed *0°C.
*1.Solid particles maximum density by weight in medium: gray sediment for *5%, mineral sediment for *0%
