Production Descripiton

Pansto pump casing of a slurry pump typically refers to the frame plate and cover plate of a double-casing slurry pump, both of which contain replaceable wear-resistant metal or rubber liners. Since they do not directly contact the slurry, these parts are not vulnerable and are usually made of high compressive strength gray cast iron or ductile cast iron. It’s important to note that the frame plate and cover plate of double-casing slurry pumps are coupled during manufacturing and not sold separately.

For single-casing structured pumps like the G series gravel dredge pumps and the SP series vertical sump pumps, their pump casings typically refer to the volute casings, which directly contact the pumped slurry. High-chrome alloy materials are generally chosen for their construction.

Cover Plate is in suction end of split casing slurry pump. It’s the outer shell of the radial subdivision, and combined with Frame plate together make up the complete pump body. Cover Plate is under pressure of pump cavity, and at the same time bear the force of pipeline. So Cover plate need to have more higher request for strength.

Frame plate is in drive end of split casing slurry pump. It connects with Frame plate liner insert and beside the Bearing assembly. Same as the cover plate, Frame plate also bear the pressure of pump cavity. The working pressure of slurry pump is decided by the loading capability of frame plate, So the right materials of slurry pump frame plate is very important.

FAQ

What is the difference between pump casing and volute?

A pump casing is often referred to as a volute. A volute is a spiral-like geometry with an increasing through-flow area, reducing the velocity of the fluid and increasing the static pressure. The fluid exiting the impeller is then diffused towards the casing discharge nozzle.

What are the advantages of a volute pump?

Wide operating range in which the pumps can operate.
The combination of a steel-mounted rotor unit placed in a volute made of concrete allows larger flows to be pumped with less quantity of pumps. …
The CVP design has a high degree of reliability and higher efficiency.

What is the difference between casing and impeller?

A volute casing or diffuser is used to convert kinetic energy to pressure. An impeller rotates and imparts kinetic energy onto the liquid surrounding it due to friction. As the impeller rotates, the liquid moves towards the outer periphery of the impeller and its kinetic energy is changed to pressure.

What is the service life of the pump casing?

As the strongest part of the pump body, the pump casing has a service life of up to 10 years unless it is corroded or damaged.
