Multjector vacuum pumps MRVA and MRVAC series in stainless steel with CIP option, multiple stage venturi ejectorMultijector MRVA and MRVAC
Multijector Pumps in Stainless Steel

Multijectors of the MRVA- and MRVAC-series are three stage ejectors in a round stainless steel design. This Multijector-type offers an enormous suction performance of up to 4.5 times the used compressed air and up to -910 mbar vacuum at very compact size. As the MRVA vacuum generators are made of high-quality resistant materials (stainless steel AISI 304 and Viton-gaskets are standard, options: stainless steel AISI 316L and others, PTFEcoated gaskets), they are ideal for applications
where aggressive drawn-off media or critical ambience conditions have to be taken into consideration. Furthermore the Multijector MRVAC is the first CIP-able multiple stage ejector pump and can completely be rinsed inside from the vacuum side in installed state. The cleansing liquid leaves the MRVAC through the exhaust air opening (fitting position: exhaust air opening at the bottom). Vacuum- and exhaust air opening of the MRVAC are equipped with clamp-connection pieces.

• wear- and maintenance-free
• good chemical resistance
• easy installation
• compact size
• oil-free operation
• CIP-able

Designed for the Process Industry, where aggressive gas-media must be aspirated

Can be used for vapors/fumes, with a high content of liquid particles

Can be run with Nitrogen

As we manufacute all Multijector pumps by ourselves on modern CNC machinery, we are abel to offer Multijectors in most "exotic" materials. Just ask us.
