Centerline Mounted Overhung Centrifugal Pump

EZA/EZE(foot-mounted ,centerline-mounted) 

Advantage:

Piping stresses are transmitted more directly to the foundations and are less likely to cause misalignment and distortion of the pump.

Centerline-mounted pumps in accordance with API 610 generally have heavier construction with greater case thickness, heavier shafts, heavier bolting, and high design pressures.

Piping and driver can be left in place while the complete rotating element, including the bearing housing and stuffing box, is removed for repairs. This is called the “back pullout” feature.

Some pumps are designed with larger impeller eye areas which need less NPSH_R than bracket-mounted pumps for the same operating conditions.

Movement of the centerline is minimized as the temperature rises and coupling alignment is preserved.

EZA/EZE is API 610 OH1 and OH2 ,single stage, end suction pump with back-pull-out structure ,the pump that is completely designed according to API610 8th and VDMA24297,  which meets the standard of ISO5199& ASME 73.1. to ensure the dimensional interchangeability with other pumps. EZA/EZE  type end suction pump is EU-Flo major pumps for application of single stage end suction pump. The EZA/EZE end suction pumps are usually applied for chemical process industries, oil or liquid with less solids or solids. After being Equiped with EU-Flo optional skit, EZA/EZE also used for hot oil and light corrosive liquid and sea water.EZA/EZE type end suction pump usually has closed impeller, the semi-open and open impeller of vortex can be supplied as well .
