Unvalved Diffstak 250/2000C Vapor Pump, 230-250 V, 1Ø, 50/60 Hz
| Previous | 1 / 3 | Next |
Overview
The compact water-cooled Diffstak pumps with an integral cooled baffle offer exceptionally clean pumping with very low backstreaming, reduced outgassing, and a reduction in the number of elastomer seals required for installation.
The Edwards Diffstak 250 (ISO250 inlet) design has been proven over many years with thousands of pumps installed.
This pump has an unvalved ISO collar inlet flange and is supplied with: NW40 elbow, NW40 centering-ring, NW40 clamp, water pipe couplings and ferrules, inlet ISO 250 trapped ‘O’ ring.
* For maximum throughput
