Reliable Pump Solutions for Demanding Marine Applications
In a varied industry like marine, pumps are essential for tasks like fish handling, dredging, sewage transfer, and more. Pumps must resist corrosion and operate reliably in harsh, often remote environments.
Key Considerations
The marine industry brings unique challenges for pumps. Whether it’s for fish handling, bilge water, dredging, or sewage, each application has its own demands. You’ll need to consider factors like fluid type, solids content, flow rate, and pressure, but also the harsh marine environment itself. Corrosion resistance, ease of maintenance, and operational reliability in remote or offshore locations are all crucial. Carefully assessing these needs will ensure you specify a pump that performs reliably and safely.
Solids Handling
If your application involves solids – whether soft, abrasive, or irregular in shape – you’ll need to ensure the pump can handle them without clogging or damage. Consider the solids’ size, hardness, and concentration when specifying your pump.
Fluid supply intermittency
Inconsistent or interrupted fluid supply is common in marine environments. Ensure your pump can reliably self-prime, handle dry-run situations, and recover quickly from air entrainment or suction loss.
Corrosive Environments
Saltwater, chemicals, and harsh weather demand robust materials. Selecting pumps with corrosion-resistant construction – such as stainless steel or chemically resistant elastomers – is vital for long-term reliability in marine conditions.
Peristaltic Pumps for Marine Use
Enviroflex L Series Peristaltic Pumps are built for demanding marine environments, handling abrasive, viscous, and solid-laden fluids with ease. Their seal-less design prevents leaks and blockages, while the hose is the only wear part, simplifying maintenance. With excellent suction, self-priming, and dry-run capability, they ensure reliable, low-maintenance operation in tough conditions.
The Hose is the Heart
The hose does the pumping. We supply high-quality hoses globally, tailored to your marine application.
Up To 6” Hose Size
With hose sizes up to 150mm, the L Series handles high flow rates and larger solids—ideal for fish transfer.
Self-Priming & Dry Running
Enviroflex Peristaltic pumps self-prime and can dry-run, minimising downtime after cleaning or servicing.
Ease of Maintenance
Maintenance is straightforward – typically, just a hose replacement keeps your system running smoothly.
Shear Sensitive Handling
Peristaltic pumps are ideal when handling shear-sensitive materials. The gentle, low-shear pumping action preserves the integrity of delicate products, making them perfect for applications like live fish transfer or fragile biological sludges.
Dirty Fluid Handling
Enviroflex Peristaltic Pumps excel at handling dirty fluids containing solids, sludges, and abrasive particles. Unlike other pump types, they are less prone to clogging or ragging, ensuring reliable, low-maintenance operation in tough marine applications.
