Alfa Laval M Gear Gear Pumps

Introduction

The Alfa Laval M Gear is an external gear pump that efficiently

transfers low-volume fluids for filling applications. Precision

alignment, easy cleaning and simple maintenance make the

stainless-steel M Gear pump a solid choice for dosing, sampling

and filling machines. This proven rotary positive displacement

pump easily adapts to OEM filling machines.

Application

The Alfa Laval M Gear is designed for uninterrupted production in

a broad range of hygienic and industrial applications across the

food, chemical, personal care, and many other industries.

Benefits

•Wide performance envelope and increased pressure

capabilities cover a broad range of process requirements

•Proven performance and predictable, consistent output due to

FDA-approved contacting gears

• Increased production with reduced carbon footprint due to

high efficiency and low energy consumption

•More uptime and quick, cost-effective maintenance due to fast

dismantling for routine service or parts replacement

•Flexible, compact design for easy installation in tight spaces

and integration with OEM filling machines

Working principle

The positive displacement of the pump is created by contacting,

contra-rotating multi-lobe gears, where one gear drive drives the

secondary within a fully swept pump chamber. The pump is

capable of bi-rotational flow without requiring modification.

Fluid is carried through the pump in the cavities formed between

the contacting gear and the interior of the case. As the blades

disengage, a cavity forms, filling with fluid. As the blades engage,

the cavity diminishes, displacing fluid into the outlet port.

The gears are mounted between specially developed PTFE bush

bearings, all fitted within the main pump body to ensure precision

alignment and high-performance efficiency.
