HTB (HTBD)
Axially Split Multi-Stage Between Bearings Pump
API Class BB3

Shin Nippon Machinery, the HTB model is a horizontal type axially split, multi-stage, single suction (HTBD: double suction at 1st stage), double volute between bearings pump with centerline support. The HTB (HTBD) model is suitable for high pressures and large capacities, as well as a wide range of processes and industrial applications.

Seal chamber

Seal chamber dimensions fully conform to API682 and API610 standards, with installation of our own standard-dimension dual seals also supported.

Compact design

Casing with compact crossovers minimizes friction loss on flow passages.

Compact design

Casing with compact crossovers minimizes friction loss on flow passages.

High reliability

The opposite impeller multi-stage arrangement provides pumps with balance for thrust force. Double volute casing provides balance for internal radial force.
Additionally, full-circular construction of the bearing housing and high-precision dynamic balance ensure stable operation and long bearing life.

Easy maintenance

Overhaul can be performed without removal of main pipelines or drive assembly. Adopting a volute-type casing enables easy removal and inspection of rotors.
