High Pressure Pumps For Fire Fighting Type PAHF
The Danfoss PAHF pumps are especially designed for the high-pressure fire extinguishing industry. It is dedicated for the water mist market for both land and marine applications. The pumps are designed for operation on tap water and the size ranges from 20 ccm/rev to 40 ccm/rev and can provide a l ow from 14 to 115 l/min (3,7 to 30,3 gpm).
Two types of valves are designed for direct mounting on the pump, depending on the specific need: a check valve and a relief valve.
The axial piston principle provides very high efficiency, small and compact design and long service life.
The Danfoss pumps are water lubricated and do not involve any other lubricant, making this unique pump maintenance free over its entire service life.
Features
• Very compact and light pump (can be installed with direct coupling to an electric motor/combustion engine)
• Generates insignificant pulsations in the pressure line
• No preventive maintenance required (no periodic service like eg change of lubricant and wear parts)
• Service life 500 hours
• All parts of the pump are made of non-corrosive material and the surface is easy to clean
• Few wearing parts
• Pumps can be directly boosted, without the need of a tank
PAHF
