NFPA compliant Pump Testing facility with advance testing and calibration devices that enable us to accurately inspect and test the operation of each Centrifugal Stationery Fire Pump to the required level of compliance standard. Commonly used in the fire service as a primer pump ƒRotary gear.
Two gears that rotate in a tightly meshed pattern forming pockets As each gear tooth reaches the discharge chamber, the air or water contained in that pocket is forced out of the pump.
Centrifugal pump design is the most typical for Fire Pumps and Auxiliary Pumps in modern fire apparatus and its proven design has been used in fire apparatus for well over a century. In a basic centrifugal pump , typically a single casing, water enters through the pump inlet into the center (eye) of the impeller which is spinning on a shaft. Types of fire pumps include: horizontal split case, vertical split case, vertical in-line, vertical turbine, and end suction. For more information, see NFPA 2 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, and NFPA 7 National Electrical Code, Article 695. This standard deals with the selection and installation of pumps supplying liquid for private fire protection.
DESIGN AND CONSTRUCTION STANDARD 1. Upon completion of the pump and sprinkler piping installation, a field acceptance test shall be conducted at minimum, rate and peak loads of the fire pump by controlling the quantity of water discharged through approved test devices.
Floors shall be pitched for adequate drainage of escaping water from critical equipment. The pump room shall be provided with a floor drain that will discharge to a frost free location. With over years of progressive Peerless designing, engineering and manufacturing, our pumps are proven with thousands of single and multiple vertical pump unit installations around the world. Fire Pump with Electric Motor Fire Pump with Diesel Engine Jockey Pump Generally 1 redundancy is obtained by diesel engine-driven pumps.
Peerless Pump is one of the largest manufacturers of vertical pumps in the industry. The requirements of diesel engine-driven pumps are defined in NFPA 20. Fire pump controllers are control panels containing electrical components such as circuit breaker, switches, relays and other devices dedicated to the operation of fire pumps.
Mobile crane capable of hoisting and lowering the weight of the pump or motor. Cable sling for attaching to the pump and motor lifting eyes. Ordinary hand tools - end wrenches, socket set, screw drivers, allen wrenches, etc.
Wire brush, scraper and fine emery cloth. Thread compound and light machinery oil. When the transfer valve is in VOLUME (parallel) position, the water enters each impeller eye from a common intake and leaves through a common pump discharge. A Pump Must Not Fail If the water demand exceeds the capability of the public supply, or if no public water is available, the pump will need to start promptly in an emergency situation (such as when sprinklers are activated).
Again, the output pressure of the attached fire pump can be used as a measure of adequacy of such conditions. The starting and full load current will also be impacted by variations in the voltage.
At 1 of the rated voltage, the starting current will rise 10‐ while the full load current will go down. The number of fire - pumps installed depends on the occupancy hazard (LH, OH or HH) and specific fire installation standard. Some known can be seen in the table to the right. Armstrong Horizontal Split-case (HSC) fire pumps deploy a tilted parting design, with the casing of each pump split at a 15° angle.
