Dewatering is a critical mining operation that ensures smooth running of mines and renders the mine cost-effective. It performs a variety of functions without which valuable minerals would not be available, and additional clean water from natural sources would have to be drawn from another source.
The process – removing excess water from open bodies, pits and shafts is used in many applications. These include transportation of suspended minerals in the medium at economic cost without conveyors, trucks, or any other equipment and feeding other equipment such as cooling systems, filter presses, or attrition cells. Removal of excess water also enables access to reserves below current water level, the target of a recent project we were approached for.
We were contacted by a mining client to standardise two pumps in one of their quarries. The pumps were used to drain a pit, acquiring access to reserves of stone used in the process of cement manufacture.
The pumps were installed for a few years and were of different models from different companies. Basically, they had two pumps for the same application with different motors and pump sizes.
This presented three biggest challenges to our client:
- Lack of Redundancy – Modified power consumption and shaft sizing prevented pumps and motors from being interchangeable. As a result, power usage was higher than needed, which translated into cost savings potential.
- Excessive Spare Part Inventory – Two types of pumps to keep in inventory meant twice the quantity of spare parts to inventory.
- Long Lead Times – Industry was quoting significant lead times on the delivery of new pumps.
We worked in close consultation with the client to establish the most suitable pumps for the application. These needed to be completely interchangeable and capable of delivering the required flow and pressure at a reduced installed power. For this particular project, we established two of our XMZ end-suction horizontal centrifugal multistage dewatering pumps.
They can attain 45 bar of high pressure as well as a maximum of 400m³/hr flow. They are very resistant as well because of the added bearings on the pump head that they take away from motor stress while working.
Our end suction design horizontal multistage dewatering pumps enable an end suction configuration. For extra flexibility, the discharge flange may be at the top or either side of the casing, as the customer requires. A horizontal suction also offers strong suction performance without pipework changes.
Further, a number of closed impellers and diffusers and sacrificial wear rings enable the unit to deliver very high pressures efficiently. These also protect the casing and impellers from wear.
Producers had originally offered long lead times for replacing both the existing pumps—twice our timescales we were offering to the customer.
When approved, we delivered two multistage high-pressure pumps on motors, and an additional bareshaft pump easily fit for use when maintenance is required.
The pump is particularly designed to transfer low-viscosity clean or dirty fluids that have no solid or fibrous particles.
It is particularly ideally suited to an enormous range of uses within the industrial and marine markets. Typical fluids pumped include fresh water, sea water, and fuels like diesel, petrol, and kerosene.

About us
North Ridge Pumps are an independent manufacturer and distributor of pumps. Having been established since 1998, we have a vast array of experience having become accustomed to supplying pumps for most processes.
We work within a range of industries both UK and Internationally, specifying pumps for a wide variety of applications from the transfer of corrosive and aggressive chemicals, to dewatered sludge, viscous grease, resin, glues, food and Seawater.
Our pumps range from standard centrifugal and multistage pumps, to immersed and process overhung solid handling pumps. We also supply a wide range of positive displacement pumps including Vane, Piston, Progressing Cavity and Peristaltic enabling us to specify more than one solution for your application, but also ensuring the majority of applications remain within our reach.
We offer the following services:
Technical support – We know at times pump selection is difficult. Pump selections are made with confidence by technical sales engineers who understand your process, ensuring equipment is engineered beyond your needs.
To select the correct technical solution for your requirement, longevity of design is prioritised. If there are existing issues you need assistance with, we work with you to solve these which could be high maintenance costs, frequent service periods, repeated equipment breakdown leading to lost revenue, inconsistent flow rates, clogging or where pumped product is inconsistent.
Application experience – Due to our 20 years of application experience we work with you to ensure our pumps operate according to your desired application. Our experience means we have most likely provided a solution for a similar process previously. With proven results, we know how to achieve your outcome sooner.
As our pumps are completely configurable, we design pumps with materials according to your requirement, and to your required duty point. Pumps are engineered specifically for your process whether they be baseplate mounted, within a mobile frame or in kit form with couplings, hoses, and dispensing nozzle.
Industry knowledge – We have a thorough understanding of a range of industries through experience from supplying the offshore oil and gas market, to paper mills, chemical plants and food manufacturers to name a few.
We not only understand the importance of downtime but also what each process requires and how small design improvements specific to the nature of your industry and application can reduce downtime, facilitate maintenance and improve longevity.
If you have a process or application you require a pump for, or a process which requires improving, get in touch to see how we can help.
