Blackmer's TXH35A Series Sliding Vane Pumps feature cast-iron construction materials suitable for tank trucks and transports handling clean, nonabrasive, and noncorrosive petroleum products including fuel oil. Pumps include vertical parallel porting for piping and are installed using three-position mounting brackets. Other features include grease-lubricated ball bearings, cartridge-type mechanical seals, a hardened-steel drive shaft, symmetrical bearing support for even loading and wear, and pressure-sensitive adjustable relief valve. Self-priming and dry-run capabilities offer loading and unloading flexibility, and a sliding-vane design self-adjusts for wear to reduce maintenance and to prevent the TXH35A's removal from the truck. Pumps offer speeds to 1000 rpm, flow rates to 1136 L/min (300 gal/min), and temperatures to 115ºC (240ºF). Optional components include 3-in (76-mm) pipe flanges and hydraulic motor adaptors.
