The bearing frame on these peerless pumps feature heavy duty cast iron, or ductile iron on STP frame sizes. These are designed to have enlarged oil reservoirs that aid in superior head dissipation. The units feature bulls-eye sight glass that allows easy monitoring. The VBX bearing isolator labyrinth by Inpro seals the design. This design is good for both dynamic and static sealing by utilizing contact technology which positively seals during shutdown, but functions without contact during operation. Dowel pins are planed between frame and adapts to ensure alignment in the bearing assembly. All units are available with water cooling that have corrosion resistant fin tube heat exchangers. This helps promote maximum oil protection even at high temperatures. The STP, LTP, AND MTP pumps feature standard C Face flanges which accommodate C Face motors. This Is done to eliminate alignment problems between the bearing frame and the motor. The bearing frames also feature bosses for temperature and vibration monitoring devices.

The LVB line of peerless pumps have a fully open design. This significantly reduces clogging in the process pumps. An integral back pump reduces stuffing box pressure with pump out vanes.

This feature prolongs the mechanical life of the seal and the durability of the impeller. The pump casings are matched to the impellers to ensure high efficiency and low NPSH. The casings are sealed with Teflon O-rings to provide corrosion protection.

Every impeller is dynamically balanced and may be purchased with the keyed and bolted designs.

The inboard bearing is a single row and deep grove design. This bearing design is designed to carry only a radial load which is pressed on the shaft. It floats axially and free in the frame. The outboard bearing is double rowed and deep grooved. It is locked onto the shaft with a washer and lock nut and then secured by a snap ring in the housing. The outboard bearing handle radial and unbalanced thrust loads. Precision manufacturing ensures that the bearings and meet or exceed minimum ANSI L10 of 17,500 hours of operation.

The LVB peerless process pump shaft design is available with in solid shaft construction or with sleeve shaft construction. If you choose as shaft sleeve it is a renewable shaft sleeve which is positively drive. It is a hoot type that has a free end that allows for expansion to compensate for high temperatures. Leakage is controlled by a Teflon O-ring which is under the sleeve.

There are three options for box cover designs which all meet the most recent ANSI specifications. Self-venting and draining boar seal taper chambers are available on all sizes. Standard bore stuffing box covers which accommodate both packing and self venting seals. Large bore seal chambers are available with all pumps that are furnished with mechanical seals.

The frame adapter is made from ductile iron that offers increased safety, strength, and durability. It is fully machined rabbet fit that seals the stuffing/chamber box cover. These adapters come in 6 inch and 8 inch STP sizes and work seamlessly with the bearing frame.
