Edwards Unvalved Diffstak 63/150C Vapour Diffusion Vacuum Pump - NEW 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 63 (ISO-63 inlet) design has been proven over many years with thousands of pumps installed. The unvalved Diffstak's are for systems requiring the highest possible ultimate vacuum or for those which do not need a high vacuum valve. This pump has an unvalved ISO collar inlet flange and is supplied with: NW-10 elbow, NW-10 centering-ring, NW-10 clamp, water pipe couplings and ferrules, inlet ISO-63 Co-Seal. Pumping speed N2 150 l/s H2 225 l/s Min. backing pump displacement 5 m3h-1 Recommended backing pumping RV5 Recommended fluid Santovac 5 Fluid charge (dry) 60 ml Inlet ISO-63 Exhaust NW-10 Cooling water connection 6 mm compression fittings Heater power 0.45 kW Minimum cooling-water flow at 20°C 42 l/s Weight 5 kg Edwards Unvalved Diffstak 63/150C Vapour Diffusion Vacuum Pump - NEW B34433976 / B344-33-976 110-125V single-phase 50/60Hz B34433977 / B344-33-977 210-225V 1-phase 50/60Hz B34433978 / B344-33-978 230-250V 1-phase 50/60Hz
