Pumps of this series have the widest range of shaft seals: double gland seal (with a flushing option), hydrodynamic, single mechanical, including cartridge type seal, double mechanical seal, including cartridge type.

The choice of the seal type is prescribed by GOST 31839-2012 “General Safety Requirements” (analog to EN809:1998) and Federal Norms and Regulations.

The pump unit package can optionally include a diaphragm coupling with spacer.

The AH series pumps provide reliable operation and handling of aggressive media with a higher content of foreign impurities. Can be manufactured with an open-type impeller.

 

* This type of seal remains efficient during start-up and dry run. Hydrodynamic seal requires no maintenance for the entire period of service life of the pump, it was developed by and protected by the Federal Patent No. 2350812.
