TC-1044H TC-2 TC-3 MCAT-Series	NO OVERSPEEDING DAMAGE All Smith MCAT-series 3" flange mount truck pumps are designed for 1200 RPM maximum shaft speed and deliver comparably to other makes at 650 RPM PTO speed. This means damage associated with over-revving is eliminated and will allow for faster fuel deliveries where large meters can be utilized. SINGLE MECHANICAL SEAL The MCAT-series utilizes a SINGLE mechanical shaft seal instead of two that double shaft extended type pumps provide. HEAVY DUTY OPTIONS STANDARD All MCAT-series pumps incorporate the heavy duty NSSA option (see option page) as standard equipment. Aircraft quality steel gear sets and Tungsten Carbide idler gear shafts allow for maximum efficiency at higher differential pressures. BALANCED LOADING Unlike vane pumps that are unbalanced, especially at higher differential pressures, all MCAT-series pumps feature balanced internal porting that greatly enhances pump life. EASE OF MAINTENANCE All MCAT-series pumps feature the patented SUPERSEAL mechanical shaft seal assembly that does not have to be removed from the pump in the event the gear set needs to be replaced; no loose seal components to worry about. STRAINER DISC ON AUXILIARY INLET All MCAT-series pumps incorporate a reinforced 30-mesh strainer disc on the auxiliary inlet should the pump ever be used to self load. OVERSIZED INTERNAL BYPASS RELIEF VALVE All MCAT-series pumps are designed for minimal overpressure should the internal bypass relief valve ever open. Bypass valve porting is oversized to minimize damage due to cavitation. Internal relief valve is set at 150 psid and as such, an external bypass valve is required by the Underwriters Laboratories. OPTIONAL FLANGES All MCAT-series pumps are provided with two 90° threaded elbows for the discharge and auxiliary inlet. Optional flanges includes a blind flange for the auxiliary inlet, threaded or weld type flanges, 2" NPT, for the discharge or auxiliary inlet.
