VE-VN - API 610 / VS1 vertical pump

API 610 / VS1 Vertical pump with submerged casing for clear, toxic, corrosive and flammable liquids


VE and VN pumps are vertical single or multistage (can) pumps offering a large performance range of flows and heads.

VE and VN pumps are custom engineered and available in a wide range of materials to meet the specific operating requirements present for a large range of applications. The fully compliant version with latest edition API 610 specifications provide maximum performance and reliability for the most critical wet‐pit pump applications.

- VE : Vertical turbine pump with mixed flow impeller
- VN : Vertical pump with radial impeller

- Single or multi-stage with closed impeller(s), stages bolted together for structure integrity
- Keyed impeller(s) for proper transmission of torque loadings
- Side discharge through sump head offering a compact and structural strong configuration
- Thrust bearing oil or grease-lubricated, thrust loads fully isolated from the motor
- Column bearings lubricated by the pumped liquid or lubrication by external liquid optional
- Bearing material dependent on liquid pumped : PEEK, PTFE, carbon, silicon carbide, stellite, nitronic...
- Diffuser / turbine designs eliminate radial loads on column bearings
- Inducer / Canned configurations to meet low NPSH requirements
- Excellent hydraulic efficiency (Canned configuration : see VEC - VNC)
- Shaft sealing flexibility : packing rings, single, double or tandem-mounted mechanical seal
