Diesel Engine Water Pump, 3-inch by Hasanen
Key features include a sturdy aluminum and die-cast construction that resists corrosion and wear, supporting long-term use. The pump houses a 1.06-gallon fuel tank enabling about two hours of operation per fill, reducing refueling downtime. With a 2.3KW engine, the unit reaches up to 3600 RPM and can deliver up to 40 m³/h flow. Its design emphasizes heat dissipation through multiple ventilation holes to prevent overheating during extended runs. The model supports multiple water sources such as rivers, ponds, and reservoirs, making it suitable for irrigation, pool maintenance, and general water transfer applications.
Diesel Engine Water Pump, 2-inch Hasanen
This 2-inch variant mirrors the 3-inch model’s robust build, using durable aluminum and die-cast components for corrosion resistance and longevity. It features an efficient 2.3KW engine delivering up to 3600 RPM and a maximum flow around 40 m³/h, with a suction head of 22.97 ft and total lift of 85.3 ft. A 1.06-gallon tank provides about two hours of operation per fill, and surface fins promote rapid heat dissipation, helping sustain performance during longer pumping sessions. It suits irrigation pipelines, farm water supply, and trash water transfer tasks where higher head is needed.
4 Stroke Diesel Engine Water Pump, 7.HP (njxbrek)
Designed for heavy-duty jobs, this unit delivers up to 110 GPM flow with a total head around 98 ft and a 22.97 ft suction height. The pump uses a 0.95-gallon tank allowing longer operation between refuels. Its construction emphasizes durability for industrial or farm water supply, serving both irrigation and large water transfer needs. Expect strong performance in muddy or trash water scenarios due to the rugged 7.5HP engine and sturdy chassis.
4 Stroke Diesel Engine Water Pump, 3HP 2-inch (kunghei)
This model mirrors the high-efficiency diesel pump architecture with a 196cc engine capable of 3600 RPM and up to 40 m³/h flow. It features a 2-inch inlet/outlet, enabling straightforward connection to standard hoses and pipes, plus a 24.61-foot delivery hose. The quadrilateral base and anti-slip feet reduce vibration and improve stability in uneven work sites, contributing to reliable operation during irrigation or water transfer tasks.
OAW CR4410 Water Pump for Cummins Diesel Engine
Designed as an OE-original form, fit, and function replacement pump for Cummins engines, this unit includes gaskets and is tailored for reliability within diesel engine setups. While it serves as a pump component rather than a portable transfer unit, it provides essential compatibility for maintaining Cummins-powered irrigation or pumping systems. Warranty coverage adds confidence for maintenance and replacement cycles.
Buying Guide
- Flow rate and head height: Match required water volume (GPM or m³/h) and vertical lift to your site. Higher lifts demand more power and may reduce continuous run time between refueling.
- Fuel capacity and runtime: Larger tanks extend operation between fills but add weight and size. Consider your work duration and access to refueling.
- Durability and materials: Aluminum and die-cast components resist corrosion and wear in dirty water. A stable base and anti-vibration feet improve long-term reliability on rough terrain.
- Portability vs. power: Portable units are easier to move but may offer lower flow. For large farms or construction sites, a higher horsepower model may be preferred.
- Maintenance and parts availability: Look for models with readily available spares and replacement parts (gaskets, seals, filters) to minimize downtime.
- Use case variety: If the pump will handle trash or muddy water, check for suitable impeller design and a robust cooling system to prevent overheating during extended pumping sessions.
- Compatibility with existing equipment: For engine-driven pumps used in vehicles or stationary setups, verify OE or compatible part numbers when sourcing replacements.
- Safety and warranty: Favor models with clear safety features and a warranty or return policy to ensure support after purchase.
