Design Feature

Model BTBF The model BTBF is horizontal, radially split, multistage, single suction (BTBFD=double suction at 1st stage), double casing, diffuser guide-vane type, centerline support, between bearings barrel pump. BTBF(BTBFD) is suitable for high pressure, high temperature, high speed, (BTBFD=for low NPSH), other wide range of heavy duty process and industrial applications.

Heavy duty construction is in full compliance with API 11th edition. Seal chamber Seal chamber dimensions are in full compliance with API682 and API610 standards. Dual seals can be installed with our standard seal chamber dimension.

Easy maintenance Overhaul can be carried out without disturbing main pipings and driver. Jack bolt is furnished at rabetted fit area in order to prevent obstruction of disassembly by sticking. Special tool can be prepared to help maintenance of inner case parts as an option.

Long bearing life Hydraulic axial balance device and diffuser guide-vane design produce pumps with optimum radial and axial forces balance. This ensures smooth operation and a long bearing life.

Low vibration Full circular construction of bearing housing, well balanced rotor assembly and optimum clearance design minimizes vibration of pump. Self vent Top discharge, top suction nozzles are capable of self venting and ensure smooth start up.

Minimal variety of spare parts By standardizing our horizontal, between bearings pumps, replacement parts are interchangeable and can be provided with little or no lead time.
