WRS System Options and Accessory Packages

Processed Fluid Transfer System (PFT)

This package includes a 55 gallon plastic working tank. The tank is filled automatically by a transfer pump through a cartridge-type prefilter. The pressure drop across the cartridge filter is monitored with a pressure gauge. The pump is protected by the appropriately sized pre-pump strainer. The transfer pump system is designed with two three-way valves enabling the transfer pump to pump out the residue remaining in the working tank at the end of a process run. A high level switch is used to automatically shut off the transfer pump to avoid spills and a low level switch is used to activate the pump again. Except the tank and level switches, all components are mounted on a portable stainless steel skid. Bulkhead fittings (for feed and return lines) on the working tank are used to connect to the WRS systems. Working tanks with different capacities are available upon request.

WRS Transfer Pump

Working Tank with Level Switches (TL30)

The system can be arranged to fill-in or pump-out a tank. For the fill-in arrangement, the high level switch is used to automatically shut off the transfer pump to avoid spills and a low level switch is used to activate the pump again when the fluid level is low. For the pump-out arrangement, the transfer pump is activated when the liquid level triggers the high level switch and the low level switch is used to automatically shut off the transfer pump. Contains a compact push-in connector to connect the level switches to an electrical control box. Working tanks with different capacities are available upon request. See Option ECB for level switch control.
