, with 20-minute cycling. In case of larger vol-
ume or a higher cycling frequency, consult us.
(4) Subject to pump temperature setting.
(5) At maximum rotational speed.
(6)
Without inlet pipe extension, inlet flange is ISO-F type.
(7) With standard N2 injection device. In case of specific N2 injection device, consult us.
