Welch 5.6 CFM (158 L/Min) DuoSeal Belt Driven Dual Stage Pump 1402
Reference:
Manufacturer: Welch Pumps
Welch Belt-drive vacuum pumps are known for their ruggedness world-wide in the most demanding applications.
Rugged oil seal pumps for a wide variety of vacuum needs, including Schlenk drying lines, freeze drying, degassing, concentrations, distillations, and more. Pulley drive enables low rpm operation by reducing friction, oil temperature, and oil degradation. Its large oil reservoir minimizes contamination effects and extends maintenance intervals. Single stage pumps should not operate continuously above 50 torr. Two stage pumps should not operate continuously above 10 torr.
Key features making these pumps so reliable and durable:
Low pump rpm to reduce frictional wear while minimizing reservoir temperature to lessen chemical activity
High oil feed to pump models leads to cleanest oil lubricating the internal pump module
Large oil reservoirs dilute contaminants ingested into the pump
Belt-drive vacuum pump are available in three types: DUOSEAL, CHEMSTAR and CAPTURE.
DUOSEAL vacuum pumps are used in most common lab and industrial applications. DUOSEAL pumps are available in 6 models of two-stage vacuum pumps and 2 models of one-stage pumps.
CHEMSTAR pumps are designed to tolerate harsh chemical contamination with vital parts corrosion resistant and uses Welch Gold oil, a synthetic pump oil designed to resist chemical attack.
CAPTURE pump is used for refrigerant recovery and transfer.
On special requests, both DUOSEAL and CHEMSTAR vacuum pumps can be fomblinized for oxygen service.
Welch vacuum pump oil is specifically formulated for the unique needs of vacuum pumps. Use of non-Welch vacuum pump oil voids any performance claims and product warranties.

Applications: Schlenk lines, freeze dryers, glove boxes, degassing, vacuum ovens, high boiling point distillations, HVAC service.
The Welch 1402 is the larger DuoSeal belt-drive pump, with 5.6 cfm of displacement. That extra capacity pulls down bigger systems quickly: large freeze dryers, multi-port Schlenk manifolds, glove boxes and high-boiling distillations.
The belt drive keeps the pump at a slow 525 rpm, and its 2.1 L oil reservoir dilutes any vapour that gets past the cold trap. Together they keep the oil cleaner for longer and stretch the time between services. A cold trap ahead of the pump is still the best protection for both the oil and the vacuum level.
The pump connects with 13/16 inch (21 mm) tubing.

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.
