VF-HH Series High Head Slurry Pumps

High-Head Conveying | All-Metal Lined Design | Meets Warman® HH Standards

✔ Specifically engineered for medium-to-high head, high-pressure slurry systems in mining, power generation, chemical, and metallurgy. Wet-end components feature high-chromium alloy (Metal-lined) with exceptional abrasive and corrosive resistance.

✔ Comprehensive size coverage from 1.5/1C-HH to 8/6T-HH，delivering flow rates up to 1,152 m³/h, a maximum head of 98 meters, and power configurations up to 1,200 kW.

✔ All-metal lined design with impellers and volute liners cast from ultra-hard wear alloys，providing flat efficiency curves to meet long-distance and high-drop transport demands.

💧 ·Heavy-Duty High-Pressure Outer Casing: Thick-walled ductile iron outer casings with integrated heavy reinforcing ribs provide an extra safety margin to contain high discharge pressures.
·Rigid High-Head Shaft Assembly: Extra-large shaft diameter with minimized overhang withstands high bending moments under multi-stage or high-head loads, extending bearing lifecycle.
·Pressure-Relieving Impeller Vanes: Back-shroud expelling (deputy) vanes are geometrically optimized to relieve packing box seal pressure and reduce internal fluid recirculation in high-velocity flows.
·Shaft Sleeve with Zero-Leakage Seals: Hardened stainless steel sleeve with dual O-rings protects the shaft from high-pressure backflow and aggressive abrasive wear.
·Ultra-Hard Wear Metallurgy: Overcurrent parts are cast from premium high-chrome alloys (A05, A49, Cr27), with heat treatment ensuring hardness ≥ HRC 60 for prolonged lifecycle in high-velocity flows.
·High-Pressure Shaft Sealing Options: Adaptable to packing seals, expeller (dynamic) seals, or heavy-duty slurry mechanical seals designed to withstand high suction/gland pressures.
·Multi-Angle Discharge Branch: The discharge nozzle can be positioned at 45-degree intervals, matching eight configurations for flexible layout installation.
·Dual Bearing Lubrication configurations: Choose between oil bath or heavy-duty grease lubrication depending on the operating RPM and environmental thermal loads.
