Enviropump and Seal VIT-1000 Series “Super-ANSI” Process Pump
Pumps are the heart of most Industrial Manufacturing plants. Traditional ANSI pumps are inherently weak in design, resulting in high maintenance cost and reduced reliability.

The most common areas of failure are bearings and mechanical seals.

The VIT pumps were developed to remedy the shortcomings of these pump designs.

Whatever your needs in pumps and seals, if you are looking for long life, reduced maintenance, low life cycle cost, increased MTBF, better parts interchangeability, and reduced inventory to support your pumps and seals, we can help.

EnviroPump and Seal: Designed Not to Fail
Pumps are the hearts of process plants. And like hearts, when they fail, the process stops. Pumps wear, and they can fail in ways that can not only stop the process, but also cause hazardous accidents. There are four basic ways pumps fail: vibration, heat, poor environment, and installation errors. Enviropump and Seal’s product lines are specifically designed to mitigate all these failure modes.

Design Advantages: Centerline Supported Casing
Most ANSI pumps are designed with foot mounted casings. The mounting foot is cast into the casing, and bolts directly to the baseplate.

If the pump is operating at elevated or reduced temperatures then the casing centerline will move from its position during expansion. This can cause serious misalignment issues with the driver (which is not heating and moving at same rate as the pump).

Centerline support simply means that the pump casing is supported at the shaft centerline. This allows thermal expansion growth of the casing to be symmetric from the shaft centerline outwards. Coupling alignment is maintained regardless of the temperature variations.

All EnviroPump and Seal casings through size 4x6x13 are cast with centerline support as standard. Larger sizes will be modified to provide this feature when required.
