 NFPA
National Fire Protection Association (NFPA) was established by a group of
insurers in the USA in 1896 to minimize the effects of fire and other risks. NFPA
20 is the most wide-spread and detailed resource used worldwide in fire-fighting
systems that defines the requirements regarding the installation of the fire
pumps which are used in fire protection. NFPA 20 covers the selection,
installation, acceptance test, and operation of fire pumps.

DMVP JOCKEY PUMP SET

These systems are used to continuously keep the
fire line under pressure. They also compensate
minor leakages on the line and prevent
start-stop operations of the fire pumps. This
product is supplied together with a vertical shaft
pump, expansion tank, control panel, and other
required equipment in a set and is included in
the fire pump set.
