Layout
Centrifugal, single-stage, horizontal, A-P10 (OH2) process pumps designed for difficult operating conditions.
The spiral pump body, supported axially, is divided in a vertical plane, the suction port is located in the pump axis, and the discharge port is directed radially upwards.
The design of the pumps allows for various configurations regarding the type of seal. Externally ribbed bearing bodies with a capacious oil pan accommodate bearings with high load-bearing capacity, in which a shaft with significant stiffness is supported.
