Product Description
Hunan Sanchang Pump Industry Co., Ltd. specializes in producing ZD type high-efficiency and energy-saving self-balancing multistage pumps, D type series multistage pumps, S type series double suction pumps, DG type series boiler feed pumps, R type high temperature hot water pumps, IH series chemical pumps and a series of clean water pumps, welcome Customers come to consult!
D-type pump is multistage segmental centrifugal pump, widely applied in mine drainage, factory and urban water supply & drainage. It transports solid-free clean water or liquids with physical and chemical properties similar to clean water at medium temperature from 0℃ to 80℃, with maximum allowable inlet working pressure of 0.6 MPa.
Construction Features:
D-type horizontal multistage centrifugal pump are horizontally mounted. Except model D16-60 with vertically upward suction port, other models feature horizontal suction inlet; all D series pumps have vertically upward discharge nozzle. Axial thrust is counterbalanced by balance disc. Shaft seal is normally packing seal, and mechanical seal is optional per customer’s requirement.Type D85-67 and D155-67 adopt sleeve bearings with oil bath lubrication; all remaining models are fitted with grease-lubricated rolling bearings.
Model Description:
Example: D280-43 × 5;
D —— Sectional Multistage Clean Water Centrifugal Pump
280 —— Design rated flow: 280 m³/h
43 —— Single-stage design head: 43 m
5 —— Total number of pump stages
Rotation Direction:
Clockwise when viewed from motor end towards pump.
Material of Main Parts:
All wetted parts are cast iron; pump shaft is made of Grade 45 carbon steel.
Complete Supply Package:
Full set includes pump, motor and base frame; either shared common base or standalone pump base is available. Manufacturer supplies auxiliary fittings (discharge reducer, gate valve, foot valve, check valve) and spare parts (impeller, wear ring, diffuser sleeve, balance disc, shaft sleeve).
Structure Description:
D, DG, MD, DF, DY pumps are mainly composed of fixed parts, rotor parts, bearings and shaft seals.
1. Partial stator
It is mainly composed of water inlet section, middle section, water outlet section and guide vane, etc., and each section is tightened with a bar to form a working room. The inlet of D-type multistage pump is horizontal and the outlet is vertical upward. DG pump inlet and outlet are both vertically upward. MD, DF and DY pumps have their outlets vertically upward and their inlets are generally horizontal. As required, they can also be produced in the vertical upward direction.
2. Rotor part
It is mainly composed of shaft, impeller, balance plate and shaft sleeve. The shaft transmits power to the impeller to make it work; the balance disc is used to balance the axial force; the shaft is equipped with a replaceable sleeve to protect the shaft.
3. Bearing part
It is mainly composed of bearing body, bearing and bearing gland. In addition to 85-67, 155-67, 600-60 type pump using sliding bearings, thin oil lubrication, the rest of the pump are used rolling bearings, grease lubrication. 85-67, 155-67 can also use rolling bearing structure.
4. Shaft seal
Generally, soft packing is used for sealing, which is mainly composed of sealing body, packing and water retaining ring on water inlet section and tail cover. There is a constant pressure of water in the sealing cavity, which plays the role of water seal, water cooling and lubrication. D type pump water seal generally comes from the high pressure water in the pump, DG, MD, DF, DY type pump comes from the pressure water in the pump or external water supply. DG, MD, DF, DY type pump more mechanical seal.
5. Transmission
The pump is directly driven by the prime mover through an elastic coupling. From the prime mover end, the pump rotates clockwise.
