General Description

D/MD/DF/DY series pump is multi-stage single suction sectional centrifugal pump with excellent hydraulic model, it has advantages of high-efficiency, energy-saving, wide performance range, operating safely and steadily, low noise, long life and convenience for installing and repairing etc. It can deliver heat water, oil, corrosive or wearable medium by changing material of the pump or coupled with extra cooling system.

D series pump is used in mine and urban project for delivering clear water without solid particles or other liquids which are physically or chemically similar to clear water. The temperature of liquids must not exceed 80℃.
MD pump is used to deliver neutral water with solid particles below 1.5% (viscosity less than 0.5mm) and other sewage water. It is suitable for using in steel factory and mine etc. The temperature of liquids must not exceed 80℃.
DF pump is used for delivering corrosive liquids without solid particles, the temperature of liquids is -20℃~105℃.
DY pump is used for delivering oil and petroleum liquid without solid particles and viscosity below 120 centistokes , the temperature of liquids is -20℃~105℃.
The inlet pressure of above pumps is less than 0.6Mpa.

Performance Range
Capacity: 6.3-600m3/h
Head: 22.8-650m

Instruction of pump type
For example D(MD,DF,DY) 85-67X3
D: Multi-stage horizontal centrifugal pump
MD: Multi-stage wearable centrifugal pump
DF: Multi-stage anti-corrosive centrifugal pump
DY: Multi-stage oil centrifugal pump
85: Rate capacity is 85 m3/h
67: Rate head is 67m
3: 3 stage(3 impellers)

Type D (MD,DF,DY) pump consists of stator, rotator, bearing and shaft seal:
1. Stator: main parts is suction casing, stage casing, discharge casing and Diffusor, they are screw up by poles to become a working house. The suction direction of type D pump is horizontal, its discharge direction is upward; the discharge direction of type MD, DF, DY pumps are upward, the suction direction is horizontal, they can be made upward according to user requirement.
2. Rotor: it is consist of shaft, impeller, balance disk, and shaft sleeve etc. shaft supplied power to impeller. The axial force is balanced by disc. The shaft sleeve is mounted on shaft to protect shaft.
3. Bearing parts: it is consist of bearing body, bearing and bearing cover etc. The bearing of type 85-67,155-67,600-60 pump is sliding bearing, lubricated by dilute oil; the other pump bearing is rolling bearing, lubricated by grease.
4. Shaft seal: it is usually adopted soft packing seal, consist of sealing house on suction casing, packing , blocking water ring, the seal house have some pressure water to cool. Lubricate and seal pump. Type D pump pressure water come from pump itself, type MD, DF, DY pump pressure water is come from pump itself or outer water, type MD, DF, DY pump usually adopt mechanical seal .
The pump is driver directly by motor through coupling. View from motor end, the rotating direction of pump is clockwise.

Q:where is the water pump on a rover 400 series 1999 model?
water pumps are never an easy fix. most the time you have to take the fan off, and the radiator as well so a person has room to work. MOST water pumps are in front of the motor, towards the bottom. If you follow your radiator hoses you will find it.
Q:Kia Sorrento 2003 water pump issue?
Its a procedure to replace the water pump at the same time when the timing belt is replaced because both involve the same work, now , not all the mechanics follow this procedure, if the bearing in the water pump froze that is enough to cause mayor damage, they might be right , check your records if you were charged for water pump and belt then you have a case.
Q:how do i replace a water pump on a 96 ford windstar 3.8?
water pump are kind of difficult to replace you have to remove several parts to get to it. specially if is your uncle first time. my recommendation is if you want to do it yourself to save money, have some one (family member)that did it before, just in case. go to source i will post instructions look at Table of Contents or go all the way on the bottom of the page good luck
Q:Water supply query or water pump or motor problem?
I will 'clarify' the question, then respond----- If you have a 1HP motor connected to a water pump,; what is its lifting capability ? (like raising the water UP from a well)... At or neat 'sea level', the very ideal (perfect) pump can lift water UP from 33 feet below. To be practical, considering in-efficiencies(losses) you should plan for about 25 feet of lift. Gurgling or bubbling of air/water is a good sign that the pump can not generate the vaccum-seal to begin the flow of water(priming process). You need to provide a way to prime the pump. To prime the pump, you need to supply a flow of water INTO the pump as it is running(water must be running backward into the well, then the pump will initiate the lifting process. To prevent the need to prime the pump everytime that you turn it on, you should put a check valve at the INTAKE orifice (the very end that sticks in the well). This will hold the column of water in the pipe; preventing it from running back into the well. (A check valve allows fluid to flow in one direction only....this must be connected such that the water can only flow UPWARD, out of the well. Good luck.....if you need further assistance, do email with more pump detail/specs. Make sure that the pump is rotating in the correct direction......
Q:Black ATV silicone on water pump gasket?
Black Gasket Sealant
Q:2000 Mitsubishi Eclipse GS: Water Pump?
The water pump seal will go bad if it isn't already because you are adding plain water to the cooling system! Antifreeze has a rust inhibitor and a lubricant in it and if you don't have the correct strength mix the inside of the block rusts and then the heater core and the radiator get plugged up resulting in hundreds of dollars in repairs. The water pump if leaking will drip on the passenger side from under the timing belt cover if you let the motor idle for 5 to 10 minutes. Look for the drips on the inside of the RF tire. If the water pump is leaking the timing belt will jump and bend all the valves.
Q:getting water to new pump?
How To Prime A Pump: (Need: Gallon jug of drinking water, a roll of teflon tape, and an adjustable wrench or a pipe wrench.) A. Unplug pump (or cut OFF breaker box at pump, if one). B. Unscrew (counter-clockwise) the largest (3/4) plug on top of pump head. C. Wrap 2-3 flat turns (clockwise only) of teflon tape on threads of plug. D. Pour water into plug hole until full, and quickly start threads of plug by hand. E. Plug in or turn on pump, and finger-tighten plug (air and water will bubble out around threads as you do so) until pump picks up prime. Then wrench-tighten plug when it does. Repeat all steps, if necessary, until you have full water pressure and pump cuts off on its own. Good Luck!
Q:How can I find out how to install an auxiliary water pump on a 2003 Jetta 1.8 Turbo?
you can buy books from any local auto shops like PEP Boys or AUTOZONE.
Q:Does exercise affect the amount of salts and water pumped out of the loop of henle?
Salt impacts the osmotic interest of a cellular. this implies that once it somewhat is modern-day in severe concentrations interior the cellular, water strikes into the cellular with the aid of osmosis. This extra water getting into the cellular could reason the cellular to rupture. interior the kidneys an identical mechanism applies. whilst the concentration of NaCl is severe interior the tubules extra water is retained interior the physique. besides the incontrovertible fact that, whilst the concentration of NaCl is low interior the Kidney tubules much less water is retained by utilising the physique.
Q:What kind of water pump does the 5.5KW motor have?
With the motor pump are pump according to the actual need of work with you in the head, under the same water doubled, the motor is certainly not enough, you should this motor pump change together in order to meet the requirements of.
