The TRIVAC D 2.5E are dual stage oil sealed rotary vane vacuum pumps. The number in the designation of the pump indicates the pumping speed of this pump in m3 - h-1. These pumps are capable of pumping gases and vapours out of vessels and vacuum systems down into the fine vacuum pressure range. The standard pumps are not designed to handle oxygen at concentrations exceeding the concentration of oxygen in the atmosphere. Moreover, these pumps are not suited for pumping of hazardous gases or extremely aggressive or corrosive media. The drive motor of the TRIVAC D 2.5E is screwed directly to the bearing piece. The shaft of the pump and the shaft of the motor are linked by a coupling piece. The bearings in the inner pump body are force-lubricated sliding bearings. The oil level glass for viewing the minimum/maximum oil level and the oil drain plug as well as the name plate are located on the front of the pump. The connection components, the gas ballast knob and the oil fill plug are located on the top of the pump. 

All of our equipment is used and reconditioned.  Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
