PAS Liquid-ring self priming stainless steel pump

Key Features

Flow rate up to 240 lt/min
Head up to 60 mt
Operating temperature max 110°C
Operating pressure max 7 bar
Motors from 0.3 HP to 6 HP - 1400/2800 RPM
Entirely made of AISI 304/316 high thickness stainless steel
Suitable for aggressive liquids

Self-priming pump Liquid-ring self priming pump able to handle liquids with dissolved gases and to operate at a depth of up to 6 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 Flammable liquids For handling flammable liquids, explosion proof 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 ensure a greater safety, the pumps with Atex motors are fitted only with motors certified to operate in more hazardous environments (zone 2 category 2G), although the pump is classified for zone 2 category 3G

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.
