Pump Structure about Centrifugal Large Flow Hospital Feed Water Pump
1.Casing for Centrifugal horizontal Large flow pump farming irrigation equipment
The volute casing is split on the horizontal centerline with the suction and discharge nozzle cast integral with the pump casing. The upper casing is accurately located on the lower half by the use of dowel pins. The upper casing can be removed to inspect the interior of the pump without disturbing the pipe connections or pump alignment. The suction and discharge flanges contain tapped holes for vacuum and pressure gauge. At the bottom of the flanges, there are tapped plugs for water drainage. |
2. Impeller
The impeller is static-balance calibrated, fixed with the muff and the muff nuts in both sides and its axial position can be adjusted via the nuts and axial force gets balanced by means of the symmetrical arrangement of its blades, there may be residual axial force which is borne by the bearing at the axle end. |
3. Shaft
The pump shaft is supported by two single-column centripetal ball bearings, which are mounted inside of the bearing body on both ends of the pump and lubricated with grease. The dual-suction seal ring is used to reduce the leak at the impeller |
4. Seal Type
There is gland seal type and mechanical seal type. |
Direction of Rotation about Centrifugal Large Flow Hospital Feed Water Pump
The Horizontal large volume double suction axially spilt casing centrifugal pump moves CW viewing from the clutch to it. The pump moving CCW can also be produced.
Materials about Centrifugal Large Flow Hospital Feed Water Pump
Irrigation pump general material is cast iron, main include pump casing, pump cover, impeller, seal ring and shaft sleeve, shaft is carbon steel. We could also produce as your requirements, such as nodular cast iron, cast steel, bronze and stainless steel etc.

Centrifugal Large Flow Hospital Feed Water Pump types
Fire pumps are usually used for supply water as the fire fighting systems booster, and then ensure the continuously water supply. If on fire, can extinguishment in a quick way.
The fire pumps can have below types:
As projects:
It have fire fighting truck pump, marine fire fighting pump, construction fire fighting pump, and some other fire pumps. Different projects, will have different names, but the function is same. However the pump construction will have little different. We can choose the better solutions for different projects.
As application:
It will have water supply fire fighting pump, and booster fire pump.
Centrifugal Large Flow Hospital Feed Water Pump power loss
There only a part of the mechanical power of the centrifugal pump getting from the driver equipment, convert to the centrifugal power and then delivered to the liquid power. The another part was loss. The reasons are below:
1. Hydraulic loss: Created for the liquid impact, vortex and friction in the pump. The impact and vortex hydraulic loss is because of the the liquid change the flow direction. Besides, when the liquid flow, it will have friction when meet the pump passageway.This kind of loss depend on the length, volume, shape, and surface roughness of the passageway and the liquid flow speed and other character.
2. Volume loss: It resulted for the powered liquid will channeling are leakage. The general pump volume efficiency is 0.93~0.98%. Improve the seal ring and shaft seal construction, can reduce the volume loss and increase the volume efficiency.
3. Mechanical loss: It is caused by the friction of liquid and impeller plate surface, also named dick friction loss of impeller, and the pump shaft friction when rotated in the packing, bearing, balancing parts and other mechanical parts.
