Welch 3.4 CFM High Capacity 6 Torr Diaphragm Pump 2054 110V
Reference:
Manufacturer: Welch Pumps
The diaphragm pump consists of a pump casing and a drive motor.
The pump casing contains the drive unit and four pump heads. Each pump head contains a diaphragm and the work valves.
Two pairs of pump heads are arranged opposite each other.
The pump heads are driven via an eccentric shaft with a connecting rod.
1 to 4 stage pumps are supplied, depending upon the circuitry of the pump heads.
Welch Chemical Duty vacuum pumps use dry, oil-free membrane (diaphragm) technology to deliver faster pumping dynamics that support filtration, evaporation, drying, degassing, impregnation, and other rough vacuum applications.
There are twelve models available, with free air displacement from 0.8 cfm to 7.8 cfm, and ultimate vacuum pressure as deep as 1.5 torr. All have strong pumping dynamics to near their ultimate vacuum pressure.
DryFast family models are CSA certified; 4-head and 8-head models are cUL listed. All have 1PH motors with built in thermal protection.
Welch Chemical Duty dry vacuum pumps can be used for vacuum degassing, vacuum impregnation, rotary evaporators, vacuum ovens, vacuum filtering, solid phase extraction, falling film evaporators, rough vacuum distillations, gas recycling, leak detection, gas sampling and many other laboratory and industrial applications. 1.5/2.0 torr models can strip DMF @ 35C or be used with vacuum ovens.

The Welch 2054 is a four-head, oil-free diaphragm pump that pairs a strong 100 L/min flow with a 6 Torr ultimate vacuum. That balance makes it a good vacuum oven pump and a capable partner for rotary evaporators, where it pulls down quickly and holds vacuum near its limit.
Its PTFE chemical-duty construction handles harsh solvent vapours, and the pump runs quietly enough to sit on a bench.
Maintenance is simple and infrequent: no oil to change, and diaphragms that are quick to replace. It ships with two hose nozzles, so it connects to standard lab tubing from day one.

You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
