Vertical Slurry Pumps

The Jolly series of vertical slurry pumps are built for durability and strength. These pumps feature shafts supported above the baseplate by two or three bearings, allowing the lower part of the pump to operate without additional bearings or supports. Most submerged parts, except the internal casing and impeller components, are either rubber lined or made from Hardalloy for added resilience.

The MEC range shares similar features with the Jolly range but differs in its mounting system. Instead of cantilever brackets, these pumps are supported by a strong metallic structure with a lifting eyebolt, allowing them to be suspended vertically inside tanks or wells using a metallic rope, chain, or other suspension devices.

The AUS range also has a design similar to the Jolly series, with the added benefit of run-dry capability. This unique feature enables the pump to operate without damage, even when running dry, and it can reprime itself once the liquid level returns to normal. These pumps are ideal for applications with intermittent flow.

Rubber Lined Submersible Pumps

The Pemo Submersible Pumps are built for durability and minimal maintenance. Featuring wetted parts constructed from Hardalloy, a highly resilient iron alloy with a hardness rating over 800 HB, these pumps are designed to withstand harsh conditions. pemo submersible smaller
Ideal for demanding applications, the pumps can handle up to 7% solids (with a maximum size of 20mm). They are perfect for use in deep wells where traditional vertical pumps would be costly or impractical. These submersible pumps can be installed directly at the bottom of the well or suspended from a device, eliminating the need for masonry or special structures.

Horizontal Slurry Pumps

The AO/TD range of horizontal slurry pumps are heavy-duty, end-suction pumps, while the AO/AB and AO/AB/DC-TC models feature horizontal side suction and top discharge. All of these pumps are designed to handle challenging conditions, including aggressive fluids with large solid particles and high solid concentrations.

These pumps are equipped with double seals in a back-to-back configuration and feature a clean water flush from an external source. The pump casings and impellers are rubber lined or made from Hardalloy, ensuring durability. The AO/TD range is reinforced with stronger bearings, enhancing bearing life and reducing the need for maintenance.

All models can be powered using either a flexible coaxial joint or v-belts, with the latter offering precise control over the pump’s rotational speed. The AO/TD can handle motor power up to 160kW, while the AO/AB and AO/AB/DC-TC models can accommodate up to 250kW.

The true cost of your pump

Upfront costs are just the beginning—did you know energy and maintenance make up most of a pump’s lifetime cost? A Life Cycle Cost (LCC) analysis breaks down these expenses, showing how small changes can lead to big savings in efficiency, running costs, and carbon footprint.

Frequently Asked Questions

How do slurry pumps differ from standard centrifugal pumps?

Slurry pumps are specifically designed to handle abrasive, high-solid-content fluids, whereas standard centrifugal pumps are built for clean or lightly contaminated liquids. Key differences include:

Construction - slurry pumps are made with hardened materials (such as high-chrome alloys or rubber linings) to resist wear.

Larger passages - they have wider internal clearances to allow solids to pass through without clogging.

Slower speeds - operating at lower RPMs reduces wear and extends pump life.

Stronger seals and bearings - designed to withstand high abrasion and erosion from slurry flow.

These features make slurry pumps ideal for industries like mining, wastewater treatment and dredging, where handling tough, abrasive materials is essential.
