MVP 055-3, MVP 055-3C
The pump is equipped with four separately operating pump
stages A, B, C, D which are connected via hoses to form a
three-stage vacuum pump.
– The vacuum connection A1 is equipped as follows:
MVP 055-3 -->
hose connection DN 10
MVP 055-3C --> small flange DN 16 ISO-KF.
– Depending on the pump version, the exhaust connection
2.1. of the MVP 055-3/-3C is fitted as follows:
MVP 055-3 -->
silencer (standard), small flange
DN 16 ISO-KF (option).
MVP 055-3C --> corrugated hose DN 10 (standard),
small flange DN 16 ISO-KF (option).
3. Installation
3.1. Setting Up The Pump And Location
Be sure to select the correct pump version whe-
re the pumping of possibly aggressive media are
involved.
➡
Place pump on a smooth, even surface.
➡
Anchor the pump if it is to be erected in a stationary positi-
on.
– Avoid mechanical stresses due to rigid connections. Ins-
ert elastic hoses or resilient elements as couplings
between the pump and rigid pipes.
➡
Maximum ambient tempe12 ... +40 °C.
– Make sure ventilation is adequate if pump is installed in
a enclosure or if ambient temperature is elevated.
– If pump is installed above 1000 m above mean sea level
check compatibillity with applicable safety require-
ments, e. g. DIN VDE 0530 (motor may overheat due to
insufficient cooling).
3.2. Connection of Pumping Stages
➡
Check the hose connections for the correct type of
connecting pieces before connecting the pump to the
vacuum chamber.
– Intake and outlet connections are marked with “IN” and
“EX” respectively at the membrane heads.
Interchanging the connections will result in
impermissibly high over-pressure levels.
MVP 035-2
The pump functions on the two stage principle.
On the two membrane heads A and B the intake connection is
marked with an “IN” and the exhaust connection with an
“EX” to prevent confusion.
– The vacuum connection (intake side) is provided with a 1m
plastic hose and G 1/4“ screw (option: small flange) for
connection to a PFEIFFER turbopump.
– The exhaust connection of the MVP 035-2 is provided with
a silencer and can also retrovit to small flange connection.
