Structure:

         ZH, ZHA pump is single stage, horizontal cantilever centrifugal pump, ZH-type pump for the foot support. ZHA-type pump for the center bearing, single-suction impeller radial, axial suction and radial discharge.

         Depending on conditions, the use of front and rear wear rings and balance holes for hydraulic balancing. Stuffing box with cooling or heating fittings. Seal with packing seal can also be single face or double mechanical seal. And is equipped with cooling, flushing or sealing liquid system. Standard piping design according to API610 specifications. Suction and discharge flange of the same nominal pressure rating. Looking from the motor pump is clockwise.

     6 using self-lubricating bearing lubrication (oil ring) or forced lubrication.

     7 static metal sealing surface sealing, wound pad seals and "O" ring seal.

     8 dynamic seal for mechanical seal, wash rinse cycle way from, outside tap and rinse washing three ways.
