GEIM is authorized to manufacture fire pump motors per UL File E47088, Vol. 9, Sec. 1 (under Fire Pump QXZF and Inverter Duty PRHJ). A stainless steel embossed nameplate is bolted to each machine. Fire pump motors sit dormant for many months of the year and may be subject to temperature and barometric changes, especially with outdoor applications. This environment causes condensation to collect on metal surfaces promoting corrosion and leading to unexpected failures. Optional space heaters can be wrapped around the winding coils. They work like an electric blanket transferring a small electric current into heat to keep the motor warm, dry and ready to start when operators need them most. Class H GEGARD insulation system is designed to excel in severe environments and challenging applications where lesser designs often short circuit and cause overcurrent trips. GEIM Fire Pump Motors are especially suitable for these applications: • Horizontal Fire Pumps • In-Line Fire Pumps • End Suction Fire Pumps • Vertical Fire Pumps Technical Scope Cast Iron TEFC, TENV, ODP, WPI Enclosures Cast iron bearing cap w/ recessed slinger Ball bearings standard, Roller Bearings available 1.15 Service Factor limited by UL1004-5 Class B temperature rise (80C) Continuous Duty (S1) 3300ft (1000m) altitude Stainless steel nameplates Special voltages available Special shaft designs available Space heaters, Thermistor, thermostats, or RTD’s available Shaft grounding rings available ​
