A volute type centrifugal pump is a type of industrial pump that falls under the category of centrifugal pumps. Also known as spindle screw pumps or rotary positive displacement pumps, these pumps are specifically designed to handle high-pressure industrial applications. In this article, we will delve into the intricacies of volute type centrifugal pumps, exploring their components, working principle, and applications.

A volute pump is one of the most common types of industrial centrifugal pump. A volute pump uses a cutwater and a volute built into the pump casing to direct fluid to the discharge port, or to the next stage impeller.

# Centrifugal Pump Volute Diagram

The volute in a centrifugal pump refers to the casing that surrounds the impeller. It is a spiral-shaped chamber that gradually expands in size from the pump inlet to the discharge outlet. The main function of the volute is to convert the kinetic energy generated by the impeller into pressure energy. This design helps in efficiently directing the flow of fluid through the pump and ultimately to the discharge point.

# Single Stage Centrifugal Pump Diagram

A single-stage centrifugal pump consists of a single impeller that rotates within the pump casing. The impeller is responsible for imparting energy to the fluid by rotating at high speeds. As the fluid enters the pump, it is directed towards the center of the impeller where it is then flung outward by centrifugal force. This action creates a low-pressure zone at the center of the impeller, causing more fluid to be drawn into the pump.

# Centrifugal Pump Suction and Discharge

The suction side of a centrifugal pump is where the fluid enters the pump. This is typically located at the center of the impeller. The fluid is then accelerated by the impeller and directed towards the discharge side of the pump. The discharge side is where the fluid exits the pump at a higher pressure than when it entered. The volute casing plays a crucial role in guiding the flow of fluid from the impeller to the discharge outlet.

# Centrifugal Water Pump Diagram

A centrifugal water pump diagram typically includes the impeller, volute casing, suction inlet, and discharge outlet. The impeller is the rotating component that imparts energy to the fluid, while the volute casing helps in converting this energy into pressure. The suction inlet allows fluid to enter the pump, while the discharge outlet is where the pressurized fluid exits the pump.

# Centrifugal Pump Impeller Drawing

The impeller of a centrifugal pump is a key component that is responsible for generating the centrifugal force needed to move the fluid through the pump. Impellers can come in various designs, including open, closed, semi-open, and vortex. The impeller drawing showcases the intricate geometry and blade configuration that enables efficient fluid movement within the pump.

# How Centrifugal Pump Works

Centrifugal pumps work on the principle of centrifugal force, which is generated by the rotation of the impeller. As the impeller spins, it creates a low-pressure zone at the center, causing fluid to be drawn into the pump. The fluid is then accelerated and directed towards the outer edges of the impeller, where it is discharged at a higher pressure. The volute casing plays a crucial role in converting the kinetic energy of the fluid into pressure energy.

# Diagram of Centrifugal Pump

A volute is a curved funnel that increases in area as it approaches the discharge port. The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the volute directs this flow through to the discharge. As the fluid travels along the volute i…
