Hytrans HydroSub 150 with DAF Diesel Engine and Hose Container

General Description

The Hytrans HydroSub 150 is a mobile high-volume water pumping and transport system designed for large-scale firefighting and emergency water supply operations.

The system consists of a diesel-hydraulic power unit, a hydraulically driven floating submersible pump and a separate hook-lift container carrying approximately 1 kilometre of 150 mm large-diameter hose, together with the necessary accessories, valves, manifolds and adaptors.

HydroSub 150 Pump Unit

The HydroSub 150 is powered by a DAF six-cylinder diesel engine, which drives the hydraulic system for the floating submersible pump.

The floating pump is placed directly into an open water source, such as a canal, river, harbour or reservoir. Because the pump is submerged in the water, the system does not depend on conventional suction lift.

Technical Specifications

Manufacturer: Hytrans Systems

Model: HydroSub 150

System: Mobile high-volume water pumping system

Engine: DAF six-cylinder diesel engine

Drive system: Diesel-hydraulic

Pump: Hydraulically driven floating submersible pump

Main hose diameter: 150 mm / 6 inch

Main hose length: 1,000 metres

Hose configuration: 50 × 20 metres

Pump Performance

The pump performance of this specific HydroSub 150 configuration is:

3,000 litres/minute at 8 bar

7,000 litres/minute at 2 bar

The high-pressure operating point is suitable when pressure is required to overcome friction losses, elevation differences or longer transport distances.

The high-volume operating point provides up to approximately 7,000 litres of water per minute at a pressure of 2 bar, making it suitable for supplying very large quantities of water where high delivery pressure is not required.

Hose Container

The HydroSub is used together with a separate hook-lift hose container.

The main hose load consists of:

50 × 20 m of 150 mm large-diameter hose

This provides a total main hose length of:

50 × 20 m = 1,000 metres

The 150 mm diameter allows large quantities of water to be transported while limiting friction losses compared with conventional smaller-diameter fire hoses.

Accessories

The hose container also carries the equipment required to construct and operate the water transport system. Depending on the exact configuration, this includes:

• 150 mm hose couplings and connection pieces
• Distribution manifolds
• 150 mm to 75 mm distributors
• Gate valves
• Non-return valves
• Reducers and adaptors
• Additional 75 mm fire hoses
• Hose ramps for crossing roads
• Hose handling equipment
• Coupling tools and other hand tools

Together, these components allow the system to be adapted to different water sources, hose layouts and firefighting equipment.

Deployment and Operation

During deployment, the HydroSub 150 is positioned as close as practical to a suitable open water source. The floating submersible pump is deployed into the water and connected to the HydroSub through its hydraulic lines.

The DAF diesel engine powers the hydraulic system, which drives the floating pump. Water is then pumped from the open water source into the 150 mm large-diameter hose system.

The hose container provides 1 kilometre of hose, allowing a high-capacity water supply line to be established between the water source and the incident area.

Depending on the required pressure and flow, the HydroSub can deliver approximately:

3,000 l/min at 8 bar

or

7,000 l/min at 2 bar

At the incident site, the water can be distributed to fire engines, portable pumps, firefighting monitors or other equipment.

Applications

The HydroSub 150 system is particularly suitable for large incidents where the available hydrant network cannot provide sufficient water. Typical applications include large industrial and warehouse fires, petrochemical incidents, major building fires, wildfires, cooling operations and emergency water supply.

Summary

The Hytrans HydroSub 150 with DAF diesel engine, combined with a hook-lift container containing 50 × 20 metres of 150 mm hose, provides a complete high-volume water transport system with approximately 1 kilometre of main hose.

The specific pump configuration has two important operating points:

3,000 l/min at 8 bar

7,000 l/min at 2 bar

This combination of high flow capacity, large-diameter hose and independent diesel-hydraulic operation makes the HydroSub 150 particularly suitable for establishing a reliable large-scale water supply over considerable distances.
