摘要： A blade for mounting to a scraped surface heat exchanger drive shaft by pivotal connection with a mounting pin has a blade body having a first side and a second side, and a scraper edge and a hinge edge. At least one mounting hole extends through the blade body generally proximate at the hinge edge. An L-shaped locking track protrudes into the first set of the blade, having an entry track extending from the hinge edge and an intermediate track extending from the entry track to the mounting hole. An L-shaped locking track also protruding into the second side of the blade, has an entry track extending from the hinge edge of the blade and an intermediate track extending from the entry track to and past the mounting hole.

摘要： An improved positive displacement rotary pump apparatus and method is provided including a front cover, a rotor body forming a chamber with the front cover, a gear case supporting a pair of hollow drive shafts, and a pair of rotors disposed in the chambers and each detachably mounted to one end of a respective hollow drive shaft via a stud that extends from the rotor through the hollow shaft to a fastener. The pump can also have at least one respective face seal between each rotor and the body with at least one first rotating seal ring disposed at the backward facing face of each rotor, and at least one respective second stationary rotating seal ring disposed on a forward facing face of the pump body. The pump further has a pair of bearings that rotatably support the shaft in the gear case, with each bearing being located relative to the gear case by a respective locating ring that is axially movable relative to the gear case, so that each bearing is axially adjustable relative to the gear case. The pump also has a contoured inner relief region located adjacent one of the inlet port and the outlet port, and located next to the front of the rotor swept area to facilitate movement of material through the pumped rotor area

摘要： A rotary lobe pump includes two geared-together, counter-rotating shafts, to which are affixed rotors with interdigital lobes. Adjustment of the angular relationship of the rotors uses a clamping device within each rotor. The clamping device consists of a tapered, slotted bushing that is forced between a mating taper on the rotor and a locking device on the shaft by means of a flanged fastener mated to each pump shaft's threads.

摘要： A method and apparatus for removing or inserting a mutator shaft from a scraped surface heat exchanger assembly comprising a split shaft design to form a plurality of mutator shaft segments. Each shaft segment contains ends further connectable with one another and may be further retained via a drive pin assembly preferably comprising a plurality of drive pin mounting screws and a drive pin. The shaft segments and drive pin assembly may be further sealed to provide a sanitary working environment particularly suitable for use in the foodstuff industry.
