Pump Volutes

THE BASICS OF A PUMP VOLUTE

A volute is a pump casing found in centrifugal pumps. Its curved or spiral shape is what makes the casing unique. Its primary purpose is direct process fluid flow through the pump. The term “volute” comes from the Latin word “voluta,” which means “spiral.” This refers to the curved shape of the volute that wraps around the pump’s impeller.

 A volute needs to be constructed from durable and corrosion-resistant materials. Stainless steel, CD4 or plastic pump volutes help to withstand the high pressure and temperature conditions that are present in pumps.

THE FUNCTION OF A VOLUTE IN A PUMP

As mentioned above, the volute directs fluid flow through a centrifugal pump. Here’s how it works. As the impeller rotates, it creates that centrifugal force and pushes the fluid outward towards the volute. The curved shape of the pump’s volute helps to guide the fluid smoothly through the pump. That is the primary function, but it also helps to reduce turbulence and minimize the loss of energy.

A pump volute also helps to create a beneficial pressure differential within the pump. As the fluid moves through the volute, the curved shape of the casing accelerates the fluid and creates a high-pressure zone. It is this pressure differential that propels the fluid through the pump and eventually out of the discharge port.

TYPES OF VOLUTE CASINGS FOR PUMPS

Several types of volute casings are used in pumps, and the type of casing that is best suited for a particular application will depend on the pump’s specific design and performance requirements.

FOUR COMMON TYPES OF VOLUTE CASINGS AVAILABLE ON THE MARKET

Single volute
casings

These are really the simplest and most common types of pump volute casings. They have a single curved or spiral-shaped casing that wraps around the centrifugal pump’s impeller. Single volute casings operate best at low to moderate pressures and flow rates.

However, they are suitable for a number of applications.

Double volute
casings

Double volute casings are more complex and have two curved or spiral-shaped casings that wrap around a centrifugal pump’s impeller. Though they are more complex, they offer several benefits. Double volute casings can operate at high pressures and flow rates.

When it comes to improving the pump’s performance and efficiency, double volute casings reduce turbulence and minimize the loss of energy.

Split volute
casings

Split volute casings are somewhat similar to double volute casings, but they are specially designed to make maintenance and repair easier. Split into two separate halves that can be removed from the pump for maintenance and repair, this volute is ideal

for pumps that are difficult to access or that require frequent maintenance. Using split volute casings can greatly reduce downtime and make your pump easier to service.

Barrel volute casings

The last type of centrifugal pump volute is a barrel volute casings. These are the volutes that are used in high-pressure pumps, such as booster pumps and fire pumps. Their cylindrical casing is divided into two halves, with the impeller mounted in the center.

When you have high pressure and large volumes of processing fluids, this casing helps to improve the pump’s performance and efficiency when operating in these environments.

BENEFITS OF USING A VOLUTE CASING PUMP

Improved efficiency

The volute casing helps to guide fluid flow through the pump and creates a pressure differential that aids in the efficient operation of the pump.

Reduced turbulence and energy loss

Our bearings withstand even the harshest conditions, ensuring they’ll last for a long time.

Easy maintenance and repair

Many volute casing pumps have removable or split casings, making it far easier to access the pump’s internal components for maintenance.

Improved reliability

A high-quality volute casing can help keep your pump operating reliably and at peak performance.

Enhanced safety

The volute casing helps to prevent fluid leakage from your centrifugal pump. Reducing the risk of spills and accidents improves the safety of your operations and protects the environment.
