Lined AH pumps fit severe operating conditions of metallurgic, petroleum, petrochemical and power engineering facilities.

Designed with any type of shaft sealing:

• double gland seal (with a flushing option);
• hydrodynamic with a centrifugal device;
• single mechanical seal;
• double mechanical seal.

The choice of the seal type is prescribed by GOST 31839-2012 “General Safety Requirements” (analog to EN809:1998) and Federal Norms and Regulations.
Lower price as compared to similar pumps designed with stainless steel and alloy liquid end without compromising the performance.

 

* 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, was developed by and protected by the Federal Patent No. 2350812.
