The Diffstak design has been proven over many years with thousands of pumps installed. The cryo-cooled versions (CR - model pumps) have a liquid nitrogen cooled baffle supplied from a reservoir attached to the pump and are intended for pumping heavy vapor loads. This pump has a pneumatically actuated high vacuum isolation valve and is supplied with: NW40 elbow, NW40 centering-ring, NW40 clamp, water pipe couplings and ferrules an an inlet ISO250 trapped 'O' ring.
