General Description
DK series pump is double-stage horizontal split centrifugal pump. It is widely used for water supply and drainage of industry, municipal facilities and agriculture irrigation. It can delivery clear water or other liquid which is physically and chemically similar to clear water. The inlet pressure should less than 0.6MPa and the temperature of the liquid is -20～80℃.
Performance range
Capacity Q: 18～1368 m3/h
Head H: 100～360m
Instruction of pump type
For example 40DK130
40: outlet diameter40mm
DK: Multi -stage horizontal split centrifugal pump
130: Rate head 130m
Structure
The pump is horizontal split casing. The pump inlet and outlet are located under split surface and are horizontally located on two sides of the pump casing; their centerlines are perpendicular to the pump axis. It is unnecessary to disturb the motor and the pipeline for maintenance, so it is very convenient to operate. The pump can use rolling bearing or sliding bearing. All other pumps use rolling bearings which get lubricated with grease except type 100DK230 and 250DK240 pumps with dilute-oil. Type 250DK360 pump uses sliding bearings which get lubricated with enhanced circulation of dilute-oil attached with dilute-oil station.
The direction of rotation
The rotor rotation of type 250DK240 and 250DK360 is counter clockwise looking from the motor to the pump i.e. the inlet is on the left and the outlet is on the right. The rotor rotation of all others is clockwise。
Material of main parts
The main parts of type 250DK360 pump: Cast steel or cast stainless steel. The main parts of all others: Cast iron.
Parts Range
pump, motor, common Foundation plate , sluice valve and check valve.

- Q: coolant coming out around a tube that supplies the heater core (told its the water pump just don't see how)
- it could be a bad water pump or a hose split at the connection or a loose clamp on the hose
- Q: How can we calculate the maximum pump pressure for chilled water system for a 20 story building
- Once a closed circulating system is filled, the circulating pump needs only to deliver the pressure difference need to take care of circulation losses due to friction and to flow controls. The friction losses will be through the chiller tubes plus through the cooling coils plus thru the longest total circulation piping run. Add to this the pressure drop through the most restrictive regulating valve in the system. This cannot be determined without knowledge of the piping sizes , the components and the respective flows. To take a guess, I would say you would be looking at a circulating pressure rise through the pump of around 30 psi. The static pressure from elevation , about 0.44 pounds per ft of height will be the same in both the supply and return risers and at both the suction and and discharge connections of the pump. So the height of the building need not be considered in the circulaton pressure losses. However the pressure rating of components will need to be suitable for that static pressure. Usually pump casings and pipe fittings are rated for cold water pressures adequate to the approximate static pressure of 90-100 psig on that ground floor or even in the basement of a 200 ft high building. where the pump is assumed to be located.
- Q: 7.63Determine the isentropic efficency of a water pump when water enters as a saturated liquid at 96.5 kPa and exits at 5 MPa and 106 degrees C.Thanks
- For the best answers, search on this site https://shorturl.im/ayhr9 1] INefficiency is associated with an increase in entropy, so the term 'isentropic efficiency' bothers me 2] Find the temp corresponding to a saturation pressure of 96.5 kPa [hint: something less than 100C]. 3] Look at the entropies in and out
- Q: My water stopped working and my tank emptied. I replaced the pressure switch and the gauge. It still didn't work. The well is about 110'. I pulled the pump and replaced it (1/2 HP, 10 gpm, 2-wire). It still doesn't work. The old pump was 15 years old. The one before only lasted 7 years. The water has a lot of sediment. I have never done this before, but it seemed straightforward enough. The wires on the pump were not differentiated in any way (same color). Could I have put the wires together incorrectly? Could I have put the switch in wrong? It doesn't click on when the breaker is turned on. What else could be wrong? Could the breaker be bad? It wasn't kicked out.
- Sounds like the vertical check valve between the end of the pump line and the pressure tank is bad and allowing the water to go back down the pipe when the pump isn't running. Papaw
- Q: hi, how long does the water pump last on e65 chassi 745i (miles)
- Usually car manufacturers estimate that most car parts (like a water pump) would last the warranty period and this means 40k to 50k miles. Original water pumps from dealers which are installed during car repairs are usually warrantied for 2 years. Of course this can be voided by driver abuse such as overheating the car or low coolant level.
- Q: How hard is putting in a water pump for my 5-series on a 1-10 scale ?and how do i put it in ? details please !? i dont have a chitlon for it . ive worked a lot on this car and i do know some things about it, but not very car savy. Thank you !!
- What is easy for you may be hard for others, so I would not give the job any hardship rating. But the approximate job entails doing these...descriptions from viewpoint of person standing infront and looking towards the engine... a) remove fan blade with fan clutch by turning big nut clockwise (reverse thread) b) remove fan belt, then remove pulley attached to water pump c) remove radiator fan shroud if you can to have more space to work in d) put basin underneath engine to catch coolant and detach radiator hose connected to water pump e) remove 6 bolts holding water pump and remove pump f) clean surface of engine block to remove left over sealant/gasket g) install new pump and other removed parts in reverse order h) add coolant, bleed (using bleeder screws in thermostat housing and upper radiator hose), then top-off coolant to proper level marked on expansion tank near windshield. i) ran engine or roadtest, then recheck coolant level after overnight stay or when engine cools down.
- Q: hooking up a water pump to my tank and need a power supply
- can you be a bit more descriptive have you a pump but no way of powering it if so what type of pump what voltage where is pump
- Q: The water burst how to repair?
- The general water burst positions for the pump body, pump cover, if not very serious welding can be used to trap, at which point the attention electrode material, most of the water pump are cast iron, so the welding difficulty is not small.If it has become deformed or has split into parts, replace it.
- Q: Bought a new water pump for my turtle tank can't get it to work
- Pump has to be off Open the reservoir on the pump You have to use water already in your setup, fill a cup with it Fill the pump reservoir until full, then refill the cup, you'll need plenty of water you might need help here from someone at home, you also might need to hold pump, or the water might drain out as you work below Turn on the pump, while the pump is running,..... pour more water in reservoir until pump is pumping water. Have to close reservoir, then put pump where it belongs. In Pets Forum here, there's a sub-forum for reptiles, theres all kinds of help there for other turtle stuff. Good luck
- Q: We have a low area in our back yard. The previous owner had a pump installed. The flow switch is in the ground at the lowest point of the yard. The actual pump is 2 feet or so, higher up. We have not had to use it much. But last week, when we have the big storm, it stopped working. It some how worked again, but pumping a lot slower, then it stop pumping again. With this pump, I had to add water to get it primed. The last time I try to add water, the water drains instantly. Any one how what could be wrong with it? It was suggest a seal was broken. Thanks for your help.
- If you say that the pump is 2 feet higher you must have a hose onthe suction side of the pump it probably has a foot valve on the end of the hose it must be hung open thats why when you try to prime the the the water flows thru check to see if there is any debris holding the check valve open if there is clean it out close the valve prime with water and try to pump
