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.

Structure
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 .
Drive
The pump is driver directly by motor through coupling. View from motor end, the rotating direction of pump is clockwise.
- Q: My water pump was replaced 3 months ago,but it stopped spraying water yesterday, How do I unclog the intake / Outflow?
- Check and see if the water impeller needs to be replaced. They are only made of rubber. Best of luck.
- Q: how do I know my water pump failed. 98 mustang V6 started to leak coolant from the front lower part of the the engine. How do I know for sure my pump is bad? Did refill and kept on leaking as I manage to get home. Little help please!
- Locate the leak. If it is directly below the pump, you are right. There are many other points on the far that will leak coolant also.
- Q: Does a Insurance policy cover if your Well water pump burns out from power outage and breaks seal and burns motor?
- power outage doesn't burn out water pump. it would simply stop. so insurance would reject this. cause of burnout depends on type of pump and situation. you'll have to dig deeper for the real reason. [breaking the seal on a pump that is immersed in the water would burn it out. dollars to donut holes though that isn't covered by homeowner's insurance -- would be treated the same as a breakdown of your heating unit due to wear.]
- Q: I am having overheating issues with my 1993 3.4L V6 Camaro,Once I start the car with no AC or Heat on while at idle or driving the car will overheat, almost to the red line. When I get onto the highway it will slowly drop all the way down to operating tempeture.Also if I turn on either the AC or Heat while driving around town the car will not overheat.On my way home I turned everything off and let the car overheating, when I got home I opened the hood and the fans are going but still overheating.Also the major sympton is that the water pump will click on and off when I have AC blowing. It will click on and off every 10 seconds or so.New waterpump?
- Try a thermostat first. The heater bypasses the thermostat and the engine runs cool. Its a cheap fix and if thats not the fix go with troubleshooting the radiator, colapsed hoses, water pump! Be sure to install it correctly!
- Q: I need to get my timing belt and water pump replaced, its been 100,000 km , just wondering, what exactly these things do, i want to know more about my car, and just how much this would cost to take care of, my dealership says almost a 1000, including labour, does this seem right.
- Never get a dealership to work on your car unless you're not paying for it. Get a good garage to do it for you instead. If you're mechanically inclined you might be able to do it yourself, but im not sure how hard it is since it sounds like your timing belt powers your waterpump (just makes it more difficult, whereas my car has a separate belt that powers my WP). Otherwise you got a honda engine in there it sounds like, so it's not going to be insanely complicated.
- Q: Where can I get a water pump housing for a 1987 Dodge Dakota, A junk yard?
- Dealership
- Q: Ok, simple question, on a 1992 Jeep Cherokee 4.0. The water pump sucks water (not push) through the heater core correct? So the flow of water goes from the block, through the heater core, into the water pump, right?
- the pump does what it say pump.... it flows thru the radiator to the block and back ..... if you having a problem with heat then it could be stoped up and need a new one .... over heating therostat.... id say yes it sucks thru the motor if the hose is hook to the motor
- Q: This was asked a year ago, so just wanted to see if there were any new answers for me. And any detail of how it can be a quot;do it yourselffix would be great. We are having major surge lately and the tanks pressure gauge reads 50 if that helps. Thanks!
- I'm not clear on what is happening. Surging water pressure can mean that there is no air cushion in your water tank and the pump suddenly is overloaded. This would be indicated if the pump turns on and off in rapid sequence. If you have 50 psi then the system is certainly pressurized and it would appear that the pump is working. If there has been a loss of air cushion then depending on the type of system you have you may have to replace the expansion tank or drain and refill it to get the air cushion back. If there is a tank on your system that has a fitting that looks like the air fitting on a bicycle tire then that is where you can pump in air to restore the air cushion. If the pump constantly runs, and then blows a breaker you may also want to check the pressure switch that turns the pump on and off.
- Q: Submersible pump coupling, what does this coupling mean?
- Submersible pump, mostly in sewage sewage pump, this is more common, QJ submersible pumps generally can not use coupling devices
- Q: Any ideas on where and what type of water pump I should use for my 29 Gallon BioCube tank? It seems that the water pump is very loud and is not working the way it should. There are bubbles shooting the aquarium and I have tried everything to fix it. I am thinking of replacing the water pump all together. Any ideas on brands that would be compatible? Anyone else tried this? Please help...
- ok before replacing have you cleaned the inside, and if there are air bubbles comming out it is because it is running dry. Basically all biocubes do this, the filter pad is slowing down the water too much, so either rince it well or replace it. Also i would wash out the blue sponge right before the pump as that can hold alot of dirt as well. Then if not add more water. But if you want to replace the pump, try via aqua water pumps. they tend to be the best. owner of the BC 29 and BC 14
