DaChuan Machinery Co.,Ltd. is the ideal equipment providing power to desander,desilter,mud mixing pump.SB series centrifugal pump also can be used as feeding pump and trip pump.SB series design and configuration ensure match equipment work best .DCSB centrifugal pump adopts mechanical seal.Most parts are interchangeable providing convenience .Bellow is how to lubrication and remove the sand pump.

First

Bearing lubrication

Bearing the 30 oil lubrication, lubricating oil should add to oil mark center line.

Bearing available and lubricating oil consistent grease lubrication.

Second

Composite seal packing chamber must often lubrication, in case packing overheating and damage, general requirements once a day.

Injection lubrication oil must rotary pump shaft, in order to make its fully into the packing chamber, until the packing gland end have grease exudation so far.

remove

Remove the coupling, pressure plate assembly

Off pump shell

Demolition of impeller: first use wrench tear down impeller nut, reoccupy drawing tools or oblique iron, exit impeller.

Off pump shell

Demolition of impeller: first use wrench tear down impeller nut, reoccupy drawing tools or oblique iron, exit impeller.

Remove the shaft seal components (including plate, the packing box packing, etc.)

Composite seal sand pump this step should withdraw from vice impeller.

Remove throw mud ring, etc.

Exit sleeve

Remove the two bearing cap

Open the lock nut and lock washer or card ring, such as a bearing, pull out bearing.
