VF-G Series Sand & Gravel Pumps

Large Non-Clogging Passage | High Throughput Capacity | Meets Warman® G/GH Standards

✔ Specifically engineered for continuously handling the most difficult highly abrasive slurries containing solids too large to be pumped by standard pumps, such as gravel, pebbles, and rocks.

✔ Comprehensive size coverage from 6/4D-G to 24/20H-G，delivering flow rates up to 5,600 m³/h, a maximum head of 78 meters, and a massive solids-passing capability of up to 380 mm.

✔ Available in both G (standard) and GH (high-head) configurations，making them ideal for dredgers, river dredging, sand excavation, and metallurgical slag handling.

⛏️ ·Single-Casing Wide Passage Design: The unique single-casing construction features an extra-wide internal wet-passage, ensuring smooth passage of large solids, gravel, and rocks with zero clogging.
·Superior NPSH Performance: Hydraulically optimized impeller geometry ensures an exceptionally low Net Positive Suction Head (NPSH) requirement, allowing for high suction lift and dredging efficiency.
·Heavy-Duty Clamped Housing: Casing halves are held by heavy-duty clamp bands, allowing the discharge branch to be oriented in any direction (360 degrees) for easy piping installation and maintenance.
·Premium High-Chrome Wet Parts: Impellers, casings, and front/back liners are cast from premium high-chromium alloy (A05, A49, Cr27) to withstand extreme abrasive and erosive wear.
·Rigid Cylinder Bearing Cartridge: Cylinder bearing assembly connected by high-strength bolts allows for simple maintenance and fast, precise adjustment of impeller clearance.
·Robust Shaft and Sleeve Protection: Large diameter shaft with hardened stainless steel sleeve and dual O-ring seals protects the assembly from abrasive particle intrusion.
·Adaptable Sealing Configurations: Supports heavy-duty packing gland seals or highly efficient expeller (dynamic) seals depending on site requirements and fluid chemistry.
·High Temperature Capability: Robust metallurgy and structurally sound casings allow the pump to handle high-temperature slurry transportation (such as metal smelting slag) safely.
