Mobile Trailer Mounted Self Priming Diesel Water Pumps

Product Description:

1. Flow range: 300m ³/h-3000m ³/h, pumping head range is 10m-30m.

2. Pump body material: cast iron or stainless steel material, and the inlet and outlet of the water pump are connected by Paul's quick couplings.

3. Equipped with a vacuum assist system, there is no need to fill the pump body with water before starting up. The pump head has a detachable cleaning port for easy maintenance and cleaning.

4. The structure of the cabin is reasonable, made of high-quality galvanized steel plates with a thickness of not less than 2.0mm. Each steel plate has undergone sandblasting, rust prevention, and anti-corrosion treatment, and is coated with 300 degree high-temperature spray paint technology. The cabin is equipped with doors on both sides to meet the observation, operation, maintenance, and repair needs of the genset control system.

5.According to the size of the water pump flow supporting engine, can be customized two-wheeled or four-wheeled trailer, trailer tow bar can be applied to a variety of heights of the tractor, steering without a dead angle, easy to move, with the pull with the use of a traveling inertia braking system, travel speed: 20km/h-60km/h.

6. The unit adopts an intelligent controller that displays parameters of the diesel engine, such as water temperature, oil pressure, oil temperature, speed, etc., and sends alarm commands when faults are detected (such as high oil temperature, low oil pressure, emergency stop alarm, etc.). It is equipped with an (emergency stop) button and has overload protection and alarm stop functions for the entire genset. The operation is simple and reliable.

Performance characteristics:

1. Good self-priming performance: The self-priming height is 1 meter higher than ordinary self-priming pumps, and the self-priming time is shorter.

2. Strong sewage discharge capacity: The special impeller anti blocking design ensures strong sewage discharge capacity, ensuring high efficiency and no blockage of the pump.

3. Efficient and energy-saving: Adopting excellent hydraulic models, the efficiency is 3-5% higher than that of general self-priming pumps.

4. Compact structure: Compared with ordinary centrifugal pumps, self-priming pumps have a compact structure and simple operation, which not only saves the trouble of pouring a large amount of water before starting, but also eliminates the low valve of the inlet pipe, reduces the inlet resistance, and increases the pump's water output.

5. Crushing mechanism: capable of tearing, cutting, and smoothly discharging fibrous materials without the need for a filter screen on the pump.

6. Sealing: can ensure safe and continuous operation of the pump for a long time.

Application:

1. Urban water supply and drainage: self-priming pumps can be used in urban water supply systems to ensure that residents' water needs are met.

2. Irrigation of farmland: In agricultural production, self-priming pumps are used to extract groundwater or river water for irrigation of farmland.

3. Industrial water: industrial production process requires a large amount of water, self-priming pumps can be used to transport industrial water.

4. Chemical industry: Self priming pumps are suitable for transporting special media such as chemical, petroleum, pharmaceutical, food, etc. They are suitable for transporting media with high temperatures, corrosiveness, and high viscosity.

5. Sewage treatment: Self suction pumps can be used in sewage treatment plants to extract and treat sewage.

6. Swimming pool circulating water: The self-priming pump is suitable for the swimming pool's circulating water system to ensure clean water quality.

7. Home drainage: In the home environment, self-priming pumps can be used for basement drainage or other areas that require pumping water.

8. High-rise water supply: self-priming pumps can be used in high-rise buildings water supply system, to ensure water supply pressure.

9. Industrial circulating water: In industrial production, self-priming pumps are used for circulating cooling water systems to ensure the normal operation of equipment.

10. Infrastructure construction: In the construction of infrastructure such as roads and bridges, self-priming pumps are used to extract and transport building materials such as concrete.

11. Agricultural irrigation: Self priming pumps can be used for farmland irrigation to improve agricultural production efficiency.

Frequently Asked Questions

Q: What is the key difference between your self-priming trailer pump and your double suction split case trailer pump?

A: The trailer mounted self-priming diesel pump (this product) covers 300–3,000 m³/h at 10–30m head, is optimized for frequent repositioning, handles light fibrous material, and uses quick-couple connections for rapid deployment. The double suction split case pump covers 126–21,800 m³/h at up to 140m head, uses flanged pipe connections, and is suited for semi-permanent infrastructure-scale applications. If your project requires daily or weekly relocation, the self-priming series is the correct specification.

Q: Does the pump really start without pre-filling? How reliable is this in the field?

A: Yes. The vacuum-assist system is driven by the diesel engine and evacuates air from the pump casing and suction line before startup. The pump casing does not need to be manually filled, and no foot valve is required on the suction line. This system is designed for reliable operation from a cold dry-start condition — the same way it starts on the first day of a deployment as on the hundredth.

Q: What size solid particles can pass through the pump?

A: The pump’s crushing mechanism handles fibrous material (grass, reeds, light organic debris) and can pass solid particles up to the size specified for the selected model. Please specify your water quality profile — particle size, fibrous content, sediment load — when requesting a quotation so our engineering team can confirm appropriate impeller configuration.

Q: Can I tow this pump with a standard farm tractor or pickup truck?

A: Yes. The multi-height universal towbar is designed to connect to a range of tractor and vehicle hitch heights without modification. Trailer weight and towing capacity requirements depend on the pump/engine configuration. Our team provides trailer specification sheets with gross weight figures for each configuration.
