Liquid metering pump for hazardous locations
HL series Teledyne Isco

The new HL-Series pumps give you the same accurate, predictable flow and pressure control as our standard D-Series, while conforming to safety standards for use in UL Class I, Division 2, Groups A B C & D, T3B or Zone 2, II 3G EEx nC IIC T3 environments. Suitable for installation in locations providing adequate protection against the entry of solid foreign objects or water capable of impairing safety. The Hazardous location rating is achieved through internal design modifications including the use of brushless DC motors. This approach eliminates the need for purge boxes or other additional safety devices.

The HL controller has a keypad and LCD, as well as built-in and optional interfaces for computer control and other devices. Programming is easy and flexible, with instant access to menu screens even when the pump is running. This allows you to change operating parameters on the fly. An optional extension cable for remote operation lets you locate the pump up to 50 feet from the controller.
