Product Description
Product Description
MDSP first-stage double-suction mining self-balancing multistage pump, the first-stage impeller adopts double-suction design, which can effectively reduce the cavitation of the water pump. Due to the absence of wear and axial pulsation of the balance disc, the alignment of the impeller and the guide vane is always in a neutral state, and the efficiency will not decrease with the wear of the balance disc and the forward movement of rotor components like the common multistage pump structure. There is no balance water leakage and volume loss, on the whole, the operation efficiency and service life of the pump are improved, and the efficiency is 5-14% higher than that of the ordinary multi-stage pump.
Model Description:
MDSP -- First-stage double-suction self-balancing multistage pump for Mining Service;
280 -- Design point flow is 280 m3/h;
65 -- The head of single-stage design point is 65m;
8 -- Number of pump stages.
Rotation Direction:
Clockwise when viewing from the motor driving end toward the pump.
Material of Main Parts:
All pump wetted parts are available in wear-resistant ductile iron, cast steel and stainless steel grades including 304, 316, 316L, 2205, 2507, etc.
Supply Scope of Complete Set:
The package includes pump, motor and base frame; either common shared base or independent pump base is optional. The manufacturer also 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:
Type D, DG, MD, DF and DY consist of four core assemblies: stationary casing parts, rotor assembly, bearing assembly and shaft seal assembly.
1. Stationary Parts
Composed of suction casing, middle casing, discharge casing and diffusers; all sections are fastened together by through bolts to form pump working chambers.
D type: Horizontal suction nozzle, vertically upward discharge nozzle
DG type: Both suction and discharge nozzles point vertically upward
MD, DF, DY type: Standard horizontal suction, vertical discharge; vertical suction & discharge configuration is available upon special request.
2. Rotor Assembly
Mainly includes pump shaft, impellers, balance disc and shaft sleeves. The shaft transmits torque to drive impeller operation; balance disc counteracts axial thrust; replaceable shaft sleeves are fitted onto the shaft for shaft protection.
3. Bearing Assembly
Consists of bearing housing, rolling/sliding bearings and bearing gland.Types 85-67, 155-67, 600-60 adopt sleeve bearings with oil bath lubrication; rolling bearing design is optional for 85-67 and 155-67.All other models use rolling bearings with grease lubrication.
4. Shaft Seal
Standard configuration is soft packing seal, composed of stuffing box on suction casing and end cover, packing rings and water slinger. Pressurized sealing water is fed into stuffing box for water sealing, cooling and lubrication.
D type: Sealing water sourced from internal high-pressure pump medium
DG, MD, DF, DY type: Sealing water from internal process medium or external service water supply; mechanical seal is widely selected as alternative for these four series.
5. Drive Arrangement
The pump is directly driven by prime mover via flexible coupling. Rotation is clockwise viewed from the prime mover end.
