High thickness pump casing

High thickness steel (3 mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life

Small size

Extremely compact and lightweight pump, still maintaining its performance and high efficiency

Reduced speed

Some models are supplied with a 1400 RPM motor, which ensures a softer and more gentle pumping action

Flow reversibility

On request, a motor that can reverse its direction of rotation is supplied, to ensure full flow reversibility

Zone at risk of explosion

To operate in zones at risk of explosion, motors compliant with Atex standards are supplied

Maximum hygiene

The pump casing is internally and externally polished to ensure the highest level of hygiene and hydraulic efficiency

Stainless steel impeller

The impeller is made from microcasting of AISI 304 or 316 stainless steel. Its shape has been optimised to ensure a high hydraulic efficiency

Greater safety

To allow using P/L pumps in potentially explosive environments Atex motors are supplied

The P/L series pumps have the following features:

  • Flow reversibility available on request
  • Possibility to handle aggressive liquids
  • High thickness steel (3mm) which ensures a higher mechanical and corrosion resistance, and therefore a longer life
  • High hydraulic efficiency
  • Explosion proof motors can be provided to pump flammable liquids
  • Microcast impeller from AISI 304/306 stainless steel
  • Mechanical seal with NBR, FPM or PTFE elastomers

Their resistance to chemical aggression makes them suitable for the chemical, pharmaceutical and textile industry, while their versatility makes them suitable for the wine-food industry.

On request, pumps can be supplied on a stainless steel carriage fitted with a switch/rotation direction inverter.

The pumps can also be supplied with DIN 11851, Garolla or Macon fittings.
