Features of D Series Horizontal Multistage Pump
1. This series pump is a horizontal, single suction, multi stage centrifugal pump section, the suction is in horizontal direction, and outlet is vertical upward. Water suction, middle, discharge section, bearing housing and pump body are bolted into one strain, and select stages according to the pump head. 
2. Rotor includes shaft, impeller, shaft sleeve, balance disk, and other parts. Axis parts are connected through the flat keys and the shaft nuts. The rotor is supported by the rotor bearings or sliding bearings in both ends, the bearing does not bear axial force, axial force is balanced by the balance disc. Bearings lubricated with grease, sliding bearings lubricated with light oil, and oil ring lubrication, and cooled by circulating water. 
3. Shaft seal in the form of two kinds, mechanical seals and packing seal. When use packing seal, the packing ring should be placed at the right location, the tightness of packing must be appropriate to the liquid oozing drop by drop. Various sealing elements is in a sealed chamber, the chamber must be filled with some water, as water seal, water cooled or water lubrication. At the seal there is replacable sleeve, to protect the shaft. 
4. From the motor direction, the pump is clockwise rotation.

Q:What are the conditions for the series and parallel connection of the pumps?
Parallel pumps: the pump is required to lift the same. This effect is to increase traffic.Pumps in series: requirements are similar to the flow of water pumps. This allows you to increase the total head and recommend adding small pressure tanks during the series connection.
Q:Water pump pressure for shower?
if your sink does not need a pump, you shower won't either....most water systems are pressurized
Q:55KW how large is the water pump wiring?
Transmission within 100 meters, 70 square millimeter aluminum cable, or 50 square millimeter copper cable. If you exceed 100 meters, you'll have to add a number to the cable.
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
As long as the flow and head to meet what pump can be, the general centrifugal pump applications are more.
Q:Water pump testing old car?
ok so the termostat replace no leaks and its overheating check the fan hub is it ok if yes then replace the radiator i dont think your head gaskets are blown because water came up when temp was hot an you reved up the engine however if water had came out when water was cold or warm the i say the head gaskets were blown hope this helps
Q:how to identify water pump on Frankenstein car?
You want the pump specific to the engine. And the motor mounts specific to the vehicle. I have never seen a fan clutch that cannot be replaced separate from the water pump.
Q:does water pump back into reactor or steam generator in a nuclear power plant?
I can see why you're a little confused. There are actually 3 separate loops in most reactor designs and you can see this in the diagram. The primary heat transport loop contains the water that touches and cools the fuel and this is the water that is pumped back to the reactor where it is heated again.... It is shown in the diagram in pink. The water from the primary heat transport loop passes into a steam generator which is full of water but the water in these two systems is kept separate to ensure all radioactivity stays in the primary heat transport loop and in the containment building. Basically the pipes from the primary heat transport system pass through a large tank of water and heat the water in the tank causing it to boil. The steam is then passed out of the generator, out of containment, and into the turbine. Next it goes into a heat exchanger which is similar to the steam generator except it is used to cool the water. The cooled water then passes back into containment and into the steam generator to be boiled again. Finally, the third heat transport loop moves cold water from either a lake, ocean, or cooling tower, into the turbine building where it cools the water in the secondary heat transport loop. This water is kept completely separate from the water in the secondary heat transport loop to ensure that if the secondary loop water somehow becomes contaminated, it doesn't pass into the third loop and get into the lake, ocean, or atmosphere. I hope that clears things up :)

Q:Well Water Pump Problems?
you do not usually have to dig up a well there could be several causes Some pressure switches are low pressure cutoff type if you lost pressure the switch needs to be reset the little silver handle on the side of the pressure switch needs to be lifted until pressure builds up Lightening might have hit the casing and burned a wire or even fried the pump although with breakers and safety switches that is unlikely. If your pump has a control box either in the pump house or the basement remove the screw and take the cover off if you smell or see something burnt go to lowes and buy a new box $45 max. If the wire is burned it is most likely right at the well cap itself turn the breaker off and remove the cap carefully pull the slack wire up and check a plumber should fix for no more than $100. If the pump is gone it will require the pump to be pulled if it is a submersible this may cost you up to$1000 . If you have an above ground jet pump that lost the prime just remove the fill cap and fill with water to restart the prime Sorry for the long answer just wanted to touch all bases
