Marine Pump Casing Introduction

Pump casings serve to seal off the inside of the pump to atmosphere to prevent leakage and retain pressure. In the case of centrifugal pumps, they surround the pump rotor which transmits energy to the fluid handled via the impeller(s) mounted on the rotating shaft.

There two basic types of pump casings: volutes and diffusers. Whether we’re talking about volutes or diffusers, what all casings have in common is that they are designed to take energy in the form of velocity and convert it into pressure.

The materials of the marine pump casing have casting bronze (ZcuZn16S14/China), stainless steel 304, casting iron (HT200/China), stainless steel 316 and so on. All products are manufactured according to your drawing and requirements.

The Types of Marine Pump Casing

Type	Feature
Volutes	Volutes are designed to capture the velocity of liquid as it enters the outermost diameter of an impeller and convert the velocity of the liquid into pressure.
Difffuser	The basic function of a diffuser is similar to that of a volute. Diffuser vanes are positioned such that they begin close to the outer edge of the impeller and then gradually extend away from the impeller periphery.
