Self-priming pump

Side channel self priming pump able to handle liquids with dissolved gases and to operate at a depth of up to 5 metres

Variable flow rate

The PAS series pumps are fitted with an internal bypass, which can be adjusted to partly reduce the flow rate

Reduced speed

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

High thickness pump casing

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

Zone at risk of explosion

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

Flow reversibility

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

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

Internal suction filter

The PAS series pumps are the only pumps fitted with an internal filter that allows any impurity in the fluid to be collected. The filter can be easily removed to carry out inspection and cleaning operations

Greater safety

To allow using PAS pumps in potentially explosive environments Atex motors are supplied

The PAS series pumps have the following features:

  • Priming at a depth of up to 5 m with the pump filled
  • Flow reversibility available on request
  • Suction filter fitted to collect any impurity that may be present in the liquid
  • Suitable for handling aggressive liquids
  • Fitted with a bypass to partly adjust the flow rate/head
  • 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.
