Slurry pump maintenance tips

Each pump model is originally designed to handle a certain fluid and the pump parameters are various. Therefore, the right pump for the application is the key for long service life.

After selecting the right pump, it is important to schedule regular inspections. Regular inspection would help the pump user to monitor pump working conditions by checking the pump operating temperature, vibration and noise, etc.

Every piece of rotating equipment in a refinery needs lubrication. Therefore, workers should be aware of the lubrication level and add it if needed. If the pump needs flushing water, make sure the water is clear to avoid contamination.

Slurry Pump Material Types

CONCEPTS OF MATERIAL SELECTION

Selection of the type of materials to be used for slurry pumping applications is not a precise procedure. 

The procedure must first account for all the factors (variable characteristics) of the particular slurry. The procedure must take into account the constraints imposed by the following:

a) type of slurry pump,

b) slurry pump speed, and

c) options within the range of the slurry pump models available.

The basic data required to make a selection of the type of material is:

a) the particle sizing of the solids to be pumped,

b) the shape and hardness of these solids, and

c) the corrosive properties of the ¡°liquid¡± component of the slurry to be pumped.

The material selection for the slurry pump liners and slurry pump impellers is made from two basic types of materials:

a) elastomers, and

b) wear/erosion resistant cast alloys.

ELASTOMERS 

The criteria for selection of the three elastomers commonly used are:

a) Natural Rubber

i) Excellent erosion resistance for slurry pump liners (against solids up to 15mm size),but limited to particles of 5mm size for slurry pump impellers.

ii) May not be suitable for very sharp edged solids.

iii) May be damaged by oversized solids or trash.

iv) Slurry pump impeller peripheral speed should be less than 27.5 m/s, to avoid the thermal breakdown of the slurry pump volute liner, adjacent to the outer edge of the slurry pump impeller. (Special formulations are available to allow speeds up to 32m/s in certain cases).
