Product Description

Brief introduction

Bonve rotary lobe pumps are used by a refinery for pumping out the collecting basins. The surface water of the refinery, which consists of rainwater, production residues and safety overflows etc., is collected in these basins. The pumps were manufactured according to the API 676 for rotary positive displacement pumps in compliance with the customer's requirements. As the Bonve lobe pumps can master the required suction height of 6 m without problems, the pumps could be installed above the collecting basin.


Bonve Rotary lobe pumps are self-priming, valve less, positive displacement pumps. With speed-proportional flow, they continuously deliver trouble-free pumping of liquids of various consistencies and multiphase mixtures. They are compact and operate with low shear and low pulsation.

Bonve Rotary Lobe Pumps are used for many different applications. They are preferred for chemical industry because of low maintenance, reverse rotation, dry running avaiable and high efficiency.

 

Working principle

The parallel, 2-shaft design is common to all Rotary Lobe Pumps. The external synchronizing gear rotates the shafts in opposite directions.
The displacement rotors are fitted on the shafts within the pump casing. The clearances between the rotors and casing are minimized to completely isolate the suction and pressure areas of the pump. 
The rotation of the rotors creates a series of chambers within the pump casing. Product fills the chambers on the suction side and is rotated circumferentially to the pressure side. This produces a uniform flow from the suction to the discharge side with no need of valves. The stress to the fluid is negligible as the product is transported almost free of shear and with little pulsation and acceleration.

Structure features

The pump cavity design is so simple. All models of pumps retain simple design styles. The fast -opening pump cover is opened to provide guarantee for user maintenance personnel without disassembling the pipeline. The driver can guarantee online repair. Greatly reduced the stop time. Before and after, the upper and lower wear -resistant internal lining design, comprehensively ensure the non -wear of the pump shell and ensure long -term durability. Such a simple maintenance characteristics reduce the operating cost of the entire life cycle of the equipment.

Rotor types

Different forms of rotor design meets the diverse needs of users, and the materials of the rotor are also diverse, such as NBR rubber, EPDM rubber, FPM rubber, FFKM rubber, PU, Stainless steel, copper, PTFE, etc.
