Circular Arc Gear Pump - 80-60 Explosion-Proof High-Flow Arc Gear Pump (Nylon Gears, 3-Inch, 7.5kW 6-Pole Ex-Proof Motor)
Product Overview
The Huying Pump Industry Circular Arc Gear Pump (80-60 model) is an industrial-grade high-flow explosion-proof arc gear pump equipped with a 7.5kW 6-pole explosion-proof motor, nylon circular arc gears, and 3-inch large ports (compatible with 75mm ID pipe). It delivers a suction lift of 5 meters, head of 60 meters, and flow rate of 60 cubic meters per hour (~1000 liters/min). Built with heavy-duty cast iron casing and certified Ex-proof motor, it is optimized for large-volume transfer of diesel, kerosene, low-viscosity lubricants, hydraulic fluid, and similar oils. Ideal for oil depots, gas stations, chemical plants, ports, ship bunkering, and heavy machinery fluid handling. As a premium high-capacity model in Huying's professional explosion-proof pump series, it offers massive flow, long-distance delivery, certified safety, and robust performance for high-risk, high-load, continuous-duty applications.
Primary Uses
- Oil Depot & Gas Station High-Volume Loading: Fast transfer from storage tanks to tank trucks, ships, or large equipment—60 m³/h flow meets peak loading demands.
- Chemical & Petroleum Industry: Safe conveyance of kerosene, solvents, low-viscosity oils, or chemical raw materials in hazardous environments.
- Port & Marine Bunkering: Ship fueling, oil barge transfer, or port tank dispatching with large ports and high head to minimize pipeline resistance and turnaround time.
- Industrial & Heavy Machinery Fluid Transfer: Long-distance oil supply or replacement for large engineering equipment, generators, and hydraulic systems in factories, mines, and construction sites.
- Emergency & Long-Distance Oil Scheduling: Depot redistribution, emergency fuel supply, or disaster-site fluid transfer with reliable high-capacity, long-range performance.
Materials and Construction
- Pump Body Material: High-strength cast iron casing + nylon circular arc gears, wear-resistant, corrosion-resistant, and impact-proof for medium-low viscosity oils.
- Gears: High-strength nylon circular arc gears (precision machined), low noise, self-lubricating, excellent wear resistance, and anti-seize performance.
- Explosion-Proof Motor: 7.5kW 6-pole Ex d IIB T4 (or higher) rated motor, full copper windings + cooling fins, prevents spark leakage in flammable atmospheres.
- Ports & Accessories: 3-inch brass/cast iron flange ports (for 75mm ID pipe), heavy-duty cast iron base, inlet/outlet quick-connect fittings; robust build weighing approx. 120-180kg, with lifting rings/handles for hoisting.
Core Functions and Features
- Ultra-High Flow & Long Head: 60 m³/h (~1000 L/min) flow with 60m head and 5m suction lift for long-distance, large-volume oil transfer.
- Explosion-Proof Certification: Motor rated Ex d IIB T4 (or higher), safe for gasoline, kerosene, and similar flammable liquids per national standards.
- Circular Arc Nylon Gears: Low noise, self-lubricating, wear-resistant, anti-seize—smooth, long-life operation even under continuous heavy load.
- Self-Priming & Long-Range Delivery: Suction lift 5m, head 60m—efficiently draws from low-level tanks or delivers over long distances.
- Ease of Use & Maintenance: Flange ports for quick connection, fixed base mounting, simple structure for easy disassembly and servicing, motor overload protection.
