How do you disassemble a pump?
How do you disassemble a pump?
These are the steps to follow:
- Disconnect the electrical wires entering the electric motor cover.
- Disconnect the circuit pump.
- Remove the screws (1)
- Uncouple the pump unit (2) and o-ring (13)
- Unscrew the caps (3), making sure you secure the impeller using a soft belt, so as not to damage the paddles.
What is the proper way how do you start the overhauling of the pump?
Start from the impeller side. Loosen the washer and guide nut. Use a pulley to unscrew the impeller. Next, remove the mechanical seal on the impeller….If the pump is mounted vertically,
- Connect the chain block and pull the motor up.
- Check if water pressure is locked inside.
- And then open the pump.
How do you prepare a maintenance pump?
To keep pumps running properly, a regular maintenance schedule should be implemented and followed.
- DETERMINE MAINTENANCE FREQUENCY. Consult the original manufacturer’s guidelines.
- OBSERVATION IS KEY.
- SAFETY FIRST.
- MECHANICAL INSPECTION.
- LUBRICATION.
- ELECTRICAL/MOTOR INSPECTION.
- REPLACE DAMAGED SEALS AND HOSES.
What are the main parts of reciprocating pump?
The Parts of Reciprocating Pump are as follows.
- Water Sump.
- Strainer.
- Suction Pipe.
- Suction Valve.
- Cylinder.
- Piston and Piston rod.
- Crank and Connecting rod.
- Delivery valve.
What is overhauling of pump?
Pump overhauls Then the pump is disassembled and visually inspected for damage or defects. Processes such as wall thickness measurements, balance checks or pump shaft run-out checks can then also be carried out.
What is the working principle of centrifugal pump?
The pump works on the principle of the forced vortex flow. it means when a mass of liquid is rotating by an external torque, the rise in pressure head of the rotating liquid takes places. The rises in pressure head at any point is directly proportional to the velocity of the liquid at that point.
How often should a pump be serviced?
HOW OFTEN SHOULD MY HEAT PUMP BE SERVICED? Your residential heat pump should be serviced annually, ideally before the start of winter, and commercial heat pumps should be serviced either at six-monthly or three-monthly intervals, depending on use.
How to dismantle and overhaul a centrifugal pump?
Attach a warning notice to pump local supply panel. 3. Close suction and discharge valves, chain and lock hand wheels. 4. Open pump suction and discharge pipe drain valves to bilge and when water ceases to flow; crack open the pipes / pump flange joints carefully to ensure that pump has drained off and is safe for opening. 5.
Who is the inventor of the centrifugal pump?
Centrifugal pumps are one of the oldest pumps. It was invented in the mid-1800s. John Appold designed the current form of these pumps. He replaced the straight vanes of the impeller with curved blades. How does it operate? It converts mechanical energy into kinetic energy.
How does the impeller work in a centrifugal pump?
The rotating impeller converts the input of mechanical energy to kinetic energy, while the stationary volute converts this to pressure. The fluid to be pumped enters the pump through the suction pipe nozzle, where it is drawn directly to the impeller “eye” located in the center of the impeller.
When to open discharge valve on centrifugal pump?
If you are using large pumps, you may need to wait for a few seconds after turning the shaft to observe the pump’s behaviour. If the shaft is free (without any distractions), Close the discharge valve fully and start the motor.
How to overhaul a centrifugal pump step by step?
Before we understand the overhauling procedure, let’s first examine how to start the pump in the right way. Open the suction valve (suction nozzle). Ensure that the discharge valve (discharge nozzle) is kept in the closed position. Turn the pump’s power off.

Why are centrifugal pumps used in industrial operations?
Centrifugal pumps are used in several industries for transferring liquids from one point to another. With the Covid-19 lockdown, industrial operations are facing massive disruptions. If you are unable to book an appointment with a pump service engineer, you can overhaul the pumps in your plant by yourself.
