Easy-to-clean low maintenance epoxy resin injection pump for mould filling
Epoxy resins are extremely hard to pump due to their high viscosity, sensitivity to shear and fast setting on mixing. These characteristics are liable to clog the pump or fail the seals.
North Ridge Pumps were contacted by an organisation who were going to fill small moulds at the initial stage of the manufacture of test pieces using a process known as Resin Transfer Moulding (RTM).
What is resin transfer moulding?
RTM is a widely used low-pressure moulding process for producing fibre plastic composite components needing rigidity and strength. The process involves forcing a resin and catalyst mixture into a sealed mould filled with dry semi-finished fibre materials in the shape of a preform or fibre pack.
The customer needed to introduce the moulds slowly and gradually at a steady flow rate, in a very strictly controlled pressure range. No fibres in the resin should ever be put under high pressure, which would lead to warping of the mould. This, in turn, would cause premature test sample failure.
North Ridge recommended the DS-M/Lab pump – a low-flow, compact peristaltic metering pump. Best for use in laboratory or small-scale applications, the DS-M/Lab is also used on:
- Processing
Critical control of drug flow, chemical dosing, transfer of corrosive liquids, distribution and sampling of lab reagents. - Microbiology labs
Transfer of diluents, buffers, culture media and sterile solutions. - Medical and biotech
Infusion, dialysis, extracorporeal circulation and analysis of high-purity fluids.
The DS-M/Lab features a quick hose change pump head designed specifically for situations where ease of maintenance is top priority. No special tools or training are required to replace the hose – simply:
Other advantages are single-phase power supply, self-priming and dry-running without danger of damage
Due to its peristaltic nature, the pump provides full traceability and contamination-free analysis, as every chemical or blend is treated through a specific tube. Since there are no seals in the pump head, there is no danger of leakage and the hoses can be changed in minutes.
At the client's special request, the pump was also fitted with a built-in inverter so that users can have speed control or flow direction reversal when necessary.
If you need a low-maintenance solution for fluid injection, circulation or transfer, North Ridge Pumps can help you choose the right fit for your process.

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.
