Model 2019 Economical, light weight, durable diaphragm vacuum pump with PTFE contact surfaces for filtering light organic solvents, weak bases and acid solutions. Material of construction is PTFE coated aluminum, PTFE liner for the diaphragm and fluorinated plastic inlet fitting. Maximum vacuum of 24 in. Hg (200 mbar). Flow of 37 lpm@60Hz. Pump can be used to pressurize up to 18 PSIG. Includes exhaust muffler and also hose fitting to channel exhaust fumes to a fume hood.

Models 2014, 2037 and 2047 DryFast® Chemical duty PTFE diaphragm pumps are effective for filtering organic solvents, acidic and basic solutions. These rugged oil-free pumps handle aggressive vapors since they are corrosion resistant with all PTFE head construction, PTFE diaphragm, fluoroplastic valves and fittings. Built-in vacuum regulation using a bleed valve mounted on the front panel. Flow ranges from 35 lpm to 70 lpm@60Hz. Ultimate vacuum to 28.3 in. Hg (53 mbar).

Models MPC 301 E, 601 E and 602 E These one stage models of MPC chemical duty PTFE diaphragm pumps are effective for filtering organic solvents, acidic and basic solutions. The MPC models use PTFE and other fluorinated plastics for the wet-ted parts to allow aggressive solvent and acid vapors to be pumped. Flow ranges from 38 lpm to 70 lpm@50hz and ultimate vacuum pressure from 75 mbar (27.7 in. Hg) to 30 mbar (29 in. Hg). Optional vacuum regulators with gauges can be mounted on the inlet of the pump to regulate the vacuum level by way of a bleed valve.
