Industrial pump repair

Industrial pumps are devices that are used to move gases or liquids with the purpose of moving the fluid or gas by a physical or mechanical action. Many think that pumps create pressure but this is not correct. It is not the pump that causes the pressure; it is by adding resistance to any flow that causes pressure. In the industrial pump market there are several different types of pumps that are used and therefore might need to be repaired. When repairs are needed it is important to use companies that have certified technicians available.

One type of industrial pump is a hydromantic pump. This is a pump regularly used in water treatment. Many wastewater treatment centers use these to help them keep the water and environment cleaners. Because of the consequences that could be associated with a pump breaking down, most water treatment plants make sure their pumps are kept maintained and repaired to keep them running as efficiently as possible.
Positive displacement pumps are another example of industrial pumps that are used today. These pumps cause liquid to move by trapping a set amount of liquid then displacing the volume that is caught out into a discharge pipe. There can be many different types of this kind of pump. There might be rotary types like, screw pumps or shuttle block pumps or a liquid ring vacuum pump or even a Wendelkolben pump.

There is also what is classified as a dry pit submersible pump which is specifically used in applications where the pump can be left unattended and still be relied upon to work with high performance and that resist clogging. These pumps are used to pump sewage and are generally used in wastewater plants or industrial plants where solid materials are being pumped.

Businesses that have industrial pumps and motors cannot afford to have their machines broken for long periods of time. Repair companies have to be ready to step in on a minutes’ notice to help analyze the problem and come up with a repair. Repair companies understand that any downtime caused by a broken pump or motor cuts into company production and throws the company off schedule. Any industrial pump repair company will understand how critical the machines are to running the business. All repair companies will have qualified technicians able to work on most any working brand pump as well as expert customer service to help and follow up on any further needs.

A quality industrial pump repair shop should be able to provide expert service and guarantee their work 100% for any makes or model pump they repair. The repair shop that works on industrial pump repairs will probably be a complete Industrial Machine repair shop. This means that they will repair motors, pumps, gearboxes, and possible circuit board hydraulics repair. It’s possible they might also offer a full machine shop and panel shop for repairs to done in-house as well as preventive maintenance as in vibration analysis and calculating the condition of bearings in electric motors as well as checking that there is sufficient lubrication.

how to start a canned pump , centrifugal pump and a vacuum pump?

explain the procedure please

1.Centrifugal Pump:
First of all prime the pump keeping discharge valve closed and ensure that there is no entrapped air.Remember you have to prime the pump in static condition.
Then start the pump with close discharge valve .This is because of the high column head it has to withstand .If you open the discharge valve and start up the pump , then pump has to withstand the high torque which may damage the pump's motor or prime mover.Be watchful and as soon as the flow is achieved and pressure is there , then start gradually opening the discharge valve.

In case of regenerative turbine pump, you can't run the pump keeping the discharge valve close.

Bigger size pumps are equipped with star-delta starter ,so initially the pump will start at slow speed and then comes into a design speed to avoid the surge of torque.

During discharge valve closed, pump has to with stand inertia forces and little column head upto discharge valve and hence no danger of motor or pump shaft failure.

In smaller capacity pumps, you can start the pump in circulation
and establishing the pumping gradually open the discharge valve and close the circulation valve as the case may be.

It is essential that you should run the pump at its BEP .

Before doing any operation , keep in mind that you are operating the pump in a fully charged line or operating the the for the first time.

If you operating the pump for the first time , then discharge line needs to be primed by keeping the vent valve or end valve in open condition.

2.Vacuum Pump:

Place pump on flat surface REMOVE Oil Filler cap and the Filter Elements from Combination Exhaust Fitting.
-Pour oil SLOWLY to avoid OVERFLOW AND SPILL. Fill up to the center of the sight glass with INFICON approved HIGH VISCOSITY SHELL TURBO OIL T32/Equivalent.
NOTE: Oil level will rise when the pump warms up & reaches the operating temperature. Check oil level when warm & adjust if required. DO NOT OVERFILL.
-REFIT Filter Elements and Oil Fill cap, ensure the high density (thin) disc is on top. Any oil spill should be wiped with a clean dry cloth.
-REMOVE Cap from one of the inlet ports and turn the Isolation Valve to “OPEN” position.
-Turn power switch ON.
-Let the SHARK run in order to warm-up and when it is running smoothly, turn the Isolation Valve to “CLOSED” position and REPLACE cap on the inlet port.
-Turn power switch OFF and CONNECT to system.
PRIOR TO CONNECTING THE pump TO AN AC/R SYSTEM, REMOVAL OF REFRIGERANT FROM THE SYSTEM IS NECESSARY; DAMAGE TO THE PUMP MAY OCCUR IF
EVACUATION IS STARTED WHILE THE SYSTEM IS UNDER HIGH PRESSURE.
-If a vacuum gauge is being used REMOVE cap from one of the inlet ports, and ATTACH it to the intake.
-Make sure fittings and connections are tight.
-Turn the Isolation Valve to “OPEN” position.
-Turn power switch ON.
-“OPEN” Gas Ballast valve for a few minutes to help bring pump up to its normal operational temperature sooner.
IT IS VITALLY IMPORTANT THAT THE PUMP HAS REACHED ITS NORMAL OPERATIONAL TEMPERATURE (50oC-70oC / 122oF-158oF) BEFORE ANY CONDENSABLE VAPORS ARE PUMPED. FAILURE TO DO THIS MAY CONTAMINATE THE OIL AND DAMAGE THE PUMP.
The pump is NOW READY TO EVACUATE air conditioning and refrigeration systems.
NOTE: If a system leak test needs to be done, it is recommended to keep the pump running after the isolation valve is closed.
Under no circumstances should the fittings on the vacuum pump be used for refrigerant transfer, as damage will occur to the valve.

3.Canned rotor pump:/Magnetic clutch coupling pump:

It is also a centrifugal pump , but it is a seal less pump.
If external bearing cooling is employed , then 1st ensure that.Prime the pump and start as centrifugal pump.

Try the search term in any search engine as following and you will have a lot of clues regarding caned pump:
"seal less pump"
"crane chem pump"
"stork pump"
"Lowrance pump"

Utility agreement final obstacle for Jerome Village
