Gasoline Water Pumps (Motopumps)

Gasoline water pump (motopump) is a portable pump type that operates with a gasoline internal combustion engine in environments without electrical connection, providing high flow rate. ORFA Industrial offers Honda, Yamaha, Stark, Kraft brand 2-stroke and 4-stroke, clean water, dirty water, and high-pressure gasoline motopump models from stock for agriculture, irrigation, firefighting, and construction applications.

What is a Gasoline Water Pump (Motopomp)?

A gasoline water pump (motopump) is a portable water transfer device consisting of a gasoline internal combustion engine and a centrifugal pump unit combined in a single body, requiring no electrical line. It is the most practical solution for field irrigation, firefighting, construction site dewatering, flood emergency response, and general clean/dirty water transfer. ORFA Industrial offers gasoline motopump models from Honda, Yamaha, Stark, Kraft, Yamato brands in 2-stroke and 4-stroke options, with flow rates from 0.5 — 100 m³/h and discharge heads from 10 — 90 meters, available from stock.

Types of Gasoline Motopumps

Gasoline water pump types are divided into different models according to engine type, fluid characteristics, and pressure/flow rate characteristics. In ORFA's product range, you can find a suitable gasoline motopump for every application.

By Engine Type

  • 2-stroke gasoline motopump — Lightweight, fuel+oil mixture, low flow.
  • 4-stroke gasoline motopump — Lower emissions, quieter, industrial use.
  • Electric start gasoline motopump — Easy starting for large models.
  • Recoil start manual gasoline motopump — Simple, economical, field use.

By Fluid and Application

  • Clean water gasoline motopump — Irrigation, tank filling, general transfer.
  • Dirty water gasoline motopump — Construction sites, flood water, muddy water.
  • High pressure gasoline motopump — Firefighting, long-distance irrigation.
  • Fire fighting gasoline motopump — Sprinkler and hydrant emergency support.

Technical Specifications and Application Areas

For correct gasoline motopump selection, flow rate, discharge head, engine power (HP), fuel consumption, and suction/discharge connection diameter should be evaluated. A gasoline motopump model suitable for your usage scenario ensures long-lasting and efficient operation.

Technical Parameters

  • Engine power: 1.5 HP — 13 HP range.
  • Flow rate: 0.5 — 100 m³/h.
  • Discharge head: 10 — 90 m (high pressure models).
  • Inlet/outlet: 1" — 4" (25 mm — 100 mm).
  • Fuel tank: 1 — 6 L range.
  • Ignition: Manual recoil or electric start.

Application Areas

  • Agricultural and garden irrigation.

Frequently Asked Questions

What is the difference between 2-stroke and 4-stroke gasoline motopumps?

A 2-stroke gasoline motopump is lighter and more economical, but requires a fuel-oil mixture and emits more emissions. 4-stroke models use engine oil separately, are quieter, have high fuel efficiency, and are more reliable for long-term operation. 4-stroke is preferred for industrial and professional use.

What criteria should I consider when choosing a gasoline motopump?

First, the required flow rate (m³/h) and discharge head (m) should be determined. For irrigation, flow rate is a priority; for firefighting, discharge head is a priority. If the fluid is dirty, a dirty water model should be chosen; for long distances, a high-pressure model. The inlet/outlet diameter (1"-4") must be compatible with existing hoses/pipes.

Can a gasoline water pump run dry?

No. The gasoline motopump must always be operated with water inside it. Running dry causes seal burning, overheating of the impeller and casing, and mechanical deformation. The pump body must be filled with water (priming) before the first start, and the suction line should be protected with a check valve.

Which gasoline motopump is suitable for firefighting?

For firefighting gasoline motopump selection, high discharge head (60-90 m) is critical. 4-stroke, high-pressure fire series gasoline motopump models (Honda WH, Yamaha YP, Stark fire) are preferred. Models with TSE and UL certification, suitable for sprinkler systems, with electric start and automatic priming features stand out in emergency response.

Does the gasoline motopump I purchased from ORFA have a warranty?

All gasoline motopump products are covered by the manufacturer's warranty. Our stock gasoline motopump models are delivered with a 1-2 year manufacturer warranty, depending on the brand. Correct fuel usage, periodic oil changes, and using a suction line filter protect the warranty period.
