OH2 Low-Flow, High-Head Petrochemical Process Pumps (VMH03X Series)
The VMH03X series pumps are single-stage overhung heavy-duty petrochemical process pumps featuring end suction, top discharge, radially split casing, and centerline support, classified as API 610 OH2 type.
Product Features
Customized for low-flow, medium/high-head, and low-NPSHa conditions
Expands the original API-OH2 range map to cover the low-flow range
Can replace some high-speed pumps, multistage pumps, and piston pumps with head <400m
Flow range: 1~28 m³/h
Available in single-stage or two-stage overhung configurations
Single-stage head up to 200m (3000rpm), two-stage head up to 400m (3000rpm)
Achieves NPSHr ≤1.5m (3000rpm) without an inducer
Open fan impellers with optimized flow path design ensures dynamic balance of axial forces for stable low-flow operation
Reasonable clearances between the impellers and casing suit particle-laden media; optional wear-resistant coatings enhance durability
