CHEMICAL PROCESS PUMPS

Union Enterprise manufactures Chemical Process Pumps. The polypropylene volute casing is 3-piece type with full metal back plate support and self-venting, with companion flange end connection. Both SS and polypropylene casings open towards drive end, and allow easy withdrawal of the bearing frame without disturbing the pipe work. It is hydraulically balanced by back vanes. Reliable fixing of impeller on the shaft is ensured by positive locking of impeller nut by means of threaded insert. A single piece heavy-duty shaft in full SS 316 material, is used. All critical surfaces are ground to less than 0.8 micron. Threads where shaft screws into impeller are sealed by Teflon "O" ring. The shaft sealing is with either packing or mechanical seals in stuffing box. External cooling is provided for longer seal life. The inboard bearing is single row, deep groove; outboard bearing is double row, deep groove angular contact type. The bearing frame of sturdy cast iron construction provides rigid bearing alignment and shaft support.
