Series HLf Hazardous Location Pumps
Teledyne ISCO HLf-series precision syringe pumps give you accurate, predictable flow and pressure control throughout a remarkable operating range. HLf-Series pumps don't exhibit pulsation or flow anomalies typically associated with other pump types. They're specifically designed to handle aqueous and organic liquids, corrosive solutions, heated fluids, liquefied gases, viscous fluids, or slurries and pastes. All can be metered with great accuracy.
The wetted materials in the HLf pumps have been tested for chemical compatibility with these fluids: acetone, acetonitrile, ammonia, benzene, butadiene, butane, diesel fuel, ethane, ethylene, ethylbenzene, gasoline, heptane, hexane, isobutylene, isopropanol, jet fuel, methane, methanol, propane, and propylene.
The HLf controller operates up to four pumps. It 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.
