Bell & Gossett VSX double suction split-case pumps feature maintenance-free bearings, a one-piece unitized seal, a groutless base plate, and an alignment-friendly coupling. As a result, they have a reduced pump room footprint of up to 40% compared to traditional split-case and vertical inline pumps.
Bell & Gossett Series VSX Features
Simplified Service
No rigging or heavy-duty material handling equipment is necessary to access the bearing, mechanical seals, or shaft sleeves. In addition, unlike older horizontal double suction, split-case, and larger vertical inline pumps, there are no heavy top casings or motors to lift off, saving cost, reducing risk, and providing easy access to the rotating assembly.
The VSX platform makes bearing, mechanical seal, and shaft sleeve inspection easy. These components are readily accessible from both sides of the pump and can be serviced from the inboard or outboard side without disturbing the piping or the motor. In addition, just one bearing, mechanical seal, or sleeve can be replaced without disturbing the other side.
Maintenance-Free Bearings
The maintenance-free bearings eliminate the need for regular maintenance, documentation logs, over-greasing problems, and the risk of mixing greases that can cause early failure. As a result, this design reduces maintenance time and costs and helps extend pump life.
New One-Piece Unitized Seal
Bell & Gossett’s new one-piece unitized seal eliminates multiple seal components and simplifies replacement. In addition, because it uses one-piece elastomeric bellows, it has fewer parts than competitive seals, resulting in significantly fewer installation errors.
Groutless Base Plate
The groutless baseplate design saves valuable time and money to speed up installation.
Alignment-Friendly Coupling
Reduce installation time further by maximizing your alignment protection. Designed with finite element analysis to optimize performance and overall life, the easy split element design avoids the movement of hubs during inspection or replacement. Moreover, an ANSI/OSHA coupling guard surrounds the coupling to protect personnel.
ANSI/OSHA Coupling Guard
ANSI B15.1 and OSHA 1910.219 compliant coupling guard shields the coupler during operation. The VSX coupler guard is dual-designed and contains viewing windows to inspect the coupling. No more than a .25-inch opening in the guard around the rotating assembly is visible.
