API610 OH1 & OH2 Pump
Product Overview
Z series petrochemical process pump is designed according to the specifications of API610 (OH1, OH2) and VDMA24297 (light, medium and heavy type). It has four series, namely, ZA (ZAO) type, ZE (ZEO) type, ZF type and ZU type on the basis of the pressure rating.

These four series are characterized by the same hydraulic performance and bearing components.

Performance Range
Flow : up to 2,600m3/h  (11,450gpm)
Head : up to 330m  (1,080 ft)
Design Pressure: 2.5~5.0 MPa (363 ~725Psi)
Working Temperature: -80 ℃ ~ +450 ℃
Inlet Diameter : 25 ~ 400mm

Structural Features
ZA pumps Adopt the foot support and closed impeller, with the design pressure of 2.5Mpa, suitable for general industrial process. (API610 OH1 pump type);.

ZE, ZF, ZU pumps adopt the center support and closed impeller and the design pressure of ZE is 5.0Mpa, ZF 7.5Mpa, ZU 13.5Mpa, applicable to the important industrial processes at high temperature and high pressure, etc. (API610 OH2 pump type) .

ZAO pumps Adopt the foot support and open or semi-open impeller, with design pressure of 2.5Mpa, applicable to conveying all kinds of residue slurry and mediums containing particles. (API610 OH1 pump type) The hydraulic power of the series pump, selected from and improved on the base of excellent hydraulic models, enlarges the inlet caliber of pump impeller, lowers the flow rate at inlet, enhances the anti-cavitation performance and working efficiency, increases the corrosion margin of pump casing and impeller, and prolongs the service life of pump.

Standard modularization design

The back pull-out design enables the bearing pedestal including impeller and shaft seal to be removed with the volute casing left in position

Shaft sealed by cartridge mechanial seal + API flushing plans.ISO 21049/API682 seal chamber accommodates multiple seal types

The pumps with outlet diameter bigger than DN 80 (3”)  are provided with double volute casings

High radial load roller bearing. Back-to-back angular contact bearings handle axial loads

ZAO/ZEO open impeller and adjustable bearing carrier easily allow impeller clearance adjustement for high hydraulic efficiency and slurry applications

The pump rotation is clockwise viewing from the drive end

Jack screws (motor side) for an easier alignment setting

Bearing lubrication and cooling options:Oil mist / Fan cooling

Applications and Function
It is mainly used in oil refineries, petrochemical industry, cryogenic engineering, mining industry, chemical fiber and general industrial processes, power plants, large and medium-sized heating and air conditioning unit, environmental engineering, offshore industries and desalination plants, etc.
And able to transport all kinds of clean liquid or liquid containing a small amount of particles, low/high temperature liquid, and neutral or corrosive liquid.
