Peristaltic Pumps
L20 Peristaltic Pump (20mm – ¾”)
The L20 Peristaltic Pump is fitted with a 20mm internal diameter hose and comes as standard in 304 stainless steel. It features ¾” BSPT connections in 316 stainless steel and is supplied with a high-quality hose selected for compatibility with the pumped fluid, along with our specially formulated hose lubricant. The L20 is capable of handling soft solids up to 16mm and hard solids up to 3mm. Depending on the configuration, it delivers a continuous flow rate of up to 1,242 litres per hour or 1,380 litres per hour for intermittent use.
Suitable for both hygienic and industrial environments, typical applications include transferring beer, batters, and sauces in food production, as well as pigments, dyes, and adhesives in packaging and print. The L20 also performs reliably in chemical transfer, dosing, and wastewater treatment processes.
Full configuration options are detailed in the Option Summary.

Pump Advantages
Reduce friction and heat
Enviroflex Peristaltic Pumps employ a roller to compress the hose and not the more usual shoe. This reduces friction and heat in the hose, increasing hose life while reducing energy requirement.
Greater volume
Across the size range, most of the L series displace a greater volume of fluid per revolution than other pumps of the same hose bore size. This allows the pump to run more slowly for the same given flow, extending hose life and reducing pulsation.
Reduced spares cost
Pumped fluid is completely contained within the hose element (with no gaskets, seals, balls or rotors to wear or clog), reducing spares and cost, and typically lowering maintenance times compared to other pump technologies.
