Submersible slurry pump seller

A submersible slurry pump is a device which has a hermetically sealed motor closely coupled to the pump body. The whole assembly is submerged in the fluid to be pumped.

Slurry Pump is the cantilever pump structure of single stage and single suction, with the bearing housing, supporting, intermediate pipe connecting the pump hydraulic components, the water is discharged out from the drain pipe parts, pump impeller is for semi- shrouded with the agitating vane on the vane extended.

submersible pump

The submersible pumps operates in a vertical position. Although their constructional and operational features underwent a continuous evolution over the years, their basic operational principle remained the same. Produced liquids, after being subjected to great centrifugal forces caused by the high rotational speed of the impeller, lose their kinetic energy in the diffuser where a conversion of kinetic to pressure energy takes place. This is the main operational mechanism of radial and mixed flow pumps.

The pump shaft is connected to the liquid/gas separator or the protector by a mechanical coupling at the bottom of the pump. Well fluids enters the pump through an intake screen and is lifted by the pumps. Other parts include the radial bearings ( bushings ) distributed along the length of the shaft providing radial support to the pump shaft turning at a high rotational speed.

A special pump in solid control system

There are many pumps for deliver drilling fluid from a solids control equipment to another in the solids control system. A submersible slurry pump is a kind of drain pump that is heavy and robust to a certain degree than the centrifugal pump. It is used to perform applications that are abrasive and tough.

Submersible slurry pump is with structure of vertical single stage and single suction system overhung centrifugal pump, it is made of abrasion-resistant alloy, it can convey medium with high concentration particle. There is no bearing and Gland Seal between impeller and pump body, so the slurry pump is maintenance-free and heat-resistant, the slurry pump is the ideal centrifugal pump for solids control system.

The motor of submersible pump uses a drive shaft which turns an impeller, generating velocity to create the pressure needed to discharge unwanted water. Water is sucked up through the bottom of the pump and redirected into the sewer, a septic tank or simply outdoors away from the home. This is the main function of all sump pumps, submersible pumps use the slightly modified method of being underwater pump.

Submersible pumps are found in many applications. Single stage pumps are used for drainage, sewage pumping, general industrial pumping and slurry pumping. They are also popular with pond filters. Other uses for submersible pumps include sewage treatment plants, seawater handling, fire fighting (since it is flame retardant cable), water well and deep well drilling, offshore drilling rigs, artificial lifts, mine dewatering, and irrigation systems.

Reasons of Breakdown of Submersible Slurry Pumps

submersible slurry pumps

First, the submersible slurry pump does not absorb water

There are many reasons may cause submersible slurry pump doesn’t absorb water, the main causes include: suction pipe is blocked and impellers are damaged, to solve these two problems the main methods are: clean up the blockages in the suction pipe and repair or replace the impellers.

Second, the submersible slurry pump power is too large

Main causes of submersible slurry pump power too large include: excessive packing compression, pump friction, bearing damaged and too large fluid flow, the four problems solving methods are: relax packing gland bolts, adjust the pump internal clearance, repair or replace damaged bearings, adjust pump operation.

Third, the submersible slurry pump bearing heating

Causes of submersible slurry pump bearings heating are generally derived from lubricants and bearings, including lubricants are not clean, lubricants in bearings are too much or too little, bearings damaged, etc. Methods of excluding bearing heating faults are: use clean lubricants, add lubricants for the bearings based upon requirements, repair or replace bearings.

Fourth, the submersible slurry pump bearing’s life is short

Submersible slurry pump bearing life is short because there is friction within the pump, impellers imbalance, foreign bodies enters into the bearing, bearing match unreasonable, motor shaft and pump shaft misalignment, axial bending, etc. The solution is to remove the friction inside the pump, adjust the impellers balance or replace with new impellers, remove foreign bodies in the bearing, replace bearings and reassemble, adjust the motor shaft and pump shaft concentricity, replace axis.

Fifth, the submersible slurry pump noise is too large

Submersible slurry pump noise is too large because the bearing is damaged, impellers imbalance, suction pipe blocked, suction pipe inlet flow uneven. Solution to these problems is to repair or replace the bearings, adjust impellers wheel balance or replace new impellers, clean suction pipe blockages, remove the suction pipe into the air to improve the conditions of the feed pump.

Submersible slurry pump four faults and solutions

Submersible slurry pump is a kind of centrifugal pump, and play an important role in solids control system. The following is the four faults and solutions about slurry pump.

Submersible slurry pump don’t absorb water.

The reasons of submersible slurry pump don’t absorb water have many possibility, the most main reasons are due to suction pipe block and impeller damage. To solve this problem, the main method is clean suction pipe blockage and repair or replace impeller.

Submersible slurry pump power is too large.

The reasons of too large submersible slurry pump power mainly include excessive packing compaction, friction in pump, bearing damage and pump roll quantity is too large. Solutions of the four faults are unscrew packing gland bolt, adjust the gap in pump, repair or replace damaged bearing, regulating the operation of pump.

Submersible slurry pump bearing fever.

The reasons of submersible slurry pump bearing fever generally due to lubricating oil and bearing, include not clean lubricating oil, lubricating oil in bearing is too much or too little, bearing damage, etc. The main solutions are use clean lubricating oil, according to the requirements add lubricating oil for bearing, repair or replace new bearing.

Submersible slurry pump bearing life is short.

Submersible slurry pump bearing short life is due to friction in pump, impeller unbalanced, foreign body in bearing, unreasonably equip bearing, centre shaft is tortuous. Solutions are adjust impeller balance or replace new impeller, clear bearing foreign body, equip bearing again, change centre shaft.
