Description

Product Information

This Direct Drive Pump (also known as a direct drive vacuum pump) is driven by an electric motor and is manufactured by Welch. These pumps can achieve a deep vacuum and are affordably priced relative to their extreme value. The pump™ motor spins at a constant speed based on the type of motor used. Unlike a belt driven vacuum pump, these motors are directly connected to the the driveshaft of the unit. In general, electric motors usually spin the pump at either 3450 RPM or 1725 RPM. The simplistic design of these pumps helps contribute to their reduced cost, and maintenance is somewhat simpler than on some other, more complicated models.

Maintenance should be carried out on the pump based on user manual guidelines, which will greatly contribute to the longevity of the pump. Some sample applications for direct drive pumps are: Vacuum Ovens, Freeze Dryers, Centrifugal Concentrators, and more. This direct drive pump is not meant for aspiration, filtration or other applications requiring operation above 30 torr. These Welch pumps can maintain a deep vacuum while remaining portable down to .1 micron, and they have an 11.3 CFM flow rate.

A direct drive pump is a crucial piece of equipment for any lab, and they are not cheap. That is why we recommend a cold trap when using this pump to prevent condensation of contaminants building up inside. Despite the cost, it is an enormously beneficial piece of equipment for many laboratories.
