The VPL1700 multistage, vertical line shaft pump is ideal for transferring toxic liquids (e.g., chlorine, phosgene, anhydrous cyanide and other lethal fluids). Pumps are top-entry, tank-mounted for maximum safety and reliability.
Vertical, Top-Entry Tank Mounting eliminates potentially hazardous side or bottom connections.
A Gas Mechanical Seal provides the lowest fugitive emissions without complex piping, instrumentation or regulation. A complete instrumentation package is available to control the flow of buffer gas to the seal chamber and monitor critical operating parameters.
An Optional Emergency Seal isolates the storage vessel from the atmosphere should a packing or mechanical seal failure occur.
An Optional Excess Flow Check Valve operates independently to stop the flow of liquid chlorine should a downstream line rupture occur while the pump is running.
Numerous Materials of Construction are available to suit application requirements.
The Diffuser Casing Design completely balances the radial thrust. Regardless of the number of stages used, or the head developed by the pump, the radial load carried by the sleeve bearings is minimal.
An Optional Inducer can be added to reduce NPSHR to minimize tank inventory.
Typical Operating Parameters (custom designs available for limits exceeding those listed)
- Flows to 182 m3/h (800 gpm)
- Heads to 244 m (800 ft)
- Temperatures from -51°C (-60°F) to 52°C (125°F)
