What Are The Advantages Of Rotary Lobe Pumps Compared With Self-Priming Centrifugal Pumps

What are the advantages of rotor pumps compared to self-priming centrifugal pumps? Today Ace lobe pump's will take you through them.

I. Form of work

The lobe pump is a volumetric pump with a large pump chamber volume and good particle throughput.

The impeller of a self-priming centrifugal pump is driven by the pump shaft to rotate and do work on the fluid located between the blades, which is centrifuged and thrown to the periphery from the centre of the impeller.

II. Rotor/impeller

The lobe pump is an elastomeric rotor with excellent expansion and wear resistance, allowing for mixed gas-liquid-solid transport and resistance to cavitation.

Self-priming centrifugal pumps are metal impellers, which can only transport cleaner, more liquid materials, not mixed gas-liquid-solid transmission.

III. Self-priming capacity

The lobe pump has good self-priming properties and can be self-priming without pump filling, with a suction range of up to 9m.

Self-priming centrifugal pumps require pump priming and have limited self-priming capacity.

IV. Conveying capacity

The lobe pump has a three-bladed rotor with a spiral linear pattern for low pulsation, low shear and smooth delivery.

The working form of the self-priming centrifugal pump determines that this pump type conveys material with high shear and pulsation.

V. Maintenance aspects

The lobe pump is easy to maintain and can be serviced online. In addition, the extractable design of the back cover of the lobe pump allows maintenance without dismantling the pump body and piping.

Self-priming centrifugal pumps need to be dismantled for pipeline repair.

Zhejiang Ace Pump Technology Co., Ltd. is a professional supplier of spiral rotary lobe pumps and centrifugal pumps with design and development, manufacturing, sales and service in one. Our cam lobe pump products are widely used in the fields of grease, petrochemicals, clearing and sweeping tanks, underground and high-speed railway sewage, breeding sewage, food waste disposal, etc.
