Water filter

The Huckepack machines with direct cooling-system are equipped with a water inlet unit with a solenoid valve (MV), a thermostatic valve (TV) and a pressure control switch (PS) (optional).
The solenoid valve (MV) is used to stop the cooling water circulation when the machine is switchedoff.
The thermostatic valve (TV) is used to control the water flow in order to keep a stable machine temperature.
The pressure switch (PS) is used to monitor the water pressure at the cooling system of the machine
and to stop the machine if the water pressure is too low.
The water bypass valve (WBV) is used at the first machine start-up.

2.4

Radiator Cooling-Version
The Huckepack machines with radiator cooling-system are independent of the cooling water net see
Product Description [➔ 5].
The cooling liquid is circulated through the radiator (AHE) by a cooling liquid pump (CLP).
A cooling fan (AF) cools the radiator (AHE).
The thermostatic valve (TV) is used to control the water flow in order to keep a stable machine temperature.

2.5

2.6

Optional Accessories

2.6.1

Gas Ballast Valve
The gas ballast valve mixes the process gas with a limited quantity of ambient air to counteract thecondensation of vapor inside the machine.
Mixing with inert gas is also possible.
The gas ballast valve has an influence on the ultimate pressure of the machine, see Technical Data[➔ 45].

2.6.2

Inlet Filter
The inlet filter (IF) protects the machine against dust and other solids on the process gas.
The inlet filter is available with a paper cartridge (other cartridge material on request).

2.6.3'Duosec' Separator
The ‘Duosec’ separator protects the machine against corrosive gases, vapors, sticky media or dust
particles in the process gas.
When the liquid has reached the sight glass, it must be drawn off through the drain plug with thevacuum pump switched off.

2.6.4

Inlet Flange
The inlet flange has a female thread and is made of ductile cast.
Available connection size(s):– G2 for HO 429 F; HO 433 F– G3 for HO 437 F; HO 441 F

2.6.5

Discharge Silencer
The discharge silencer (SI) reduces the sound pressure level at the gas discharge (OUT) of the machine.
A drain connection (DC) is provided to drain the collected seal fluid.

DC

2.6.6

Seal Fluid Separator
The seal fluid separator reduces the sound pressure level at the gas discharge (OUT) of the machineand separates the seal fluid from the discharged gas.
The seal fluid separator is available with fleece inserts or aerolith filter elements.
The change intervals of the filter elements in the separator depend on the pumped medium or saturation.
A pressure switch (option) is to switch off the machine if the filter resistance is too high.

2.6.7

Pressure Switch "Direct Cooling"
The pressure control switch monitors the static water pressure.
The machine must be switched off when the water pressure is too low.

2.6.8

Additional Level Switch of Seal Fluid Vessel
In addition to level switch LS1(mandatory) to stop the machine if the oil level in theseal fluid vessel (SFV) is too low, an upper level switch (LS2) is available, to monitor low seal fluid level in the seal fluid vessel (SFV).

2.6.9

Liquid Flushing Device
The liquid flushing device is to flush the machine with the appropriate liquid according to the process type.
The flushing device makes it possible to clean the pump stages (LPS and HPS) from residues, polymerizing, subliming or corrosive tailings.

10 | 52

Instruction Manual HUCKEPACK HO 0429-0441 F_EN_enProduct Description​ | 2

Storage● Seal hermetically all apertures with the caps provided with the machine, or with adhesive tape
if the caps are no longer available.
● Store the machine indoors, in a dry place, away from dust and vibrations and if possible, in
original packaging, preferably at temperatures between 0 ... 40°C.

If the machine is to be stored for more than 60 days:● Drain the seal fluid vessel and refill with 3 liters of conservation oil, BUSCH part no. 0831 570
966 (5-liter packaging).
● Let the machine run for one hour or until it reaches full operating temperature, with suction
connection 90-95% closed.
● Make sure there is still some conservation oil in the bottom of the seal fluid vessel.
● Switch the machine off with the inlet closed.
Direct cooling version:● Disconnect the water supply line to the machine.
● Drain the cooling water from the cooling jackets by opening the cooling liquid drain valve(CLD).
Radiator cooling version:● Check the level of water/glycol cooling liquid, refill if necessary.
If a seal fluid separator or discharge silencer (SI) being installed:● Seal hermetically all apertures with the caps provided with the machine, or with adhesive tape
if the caps are no longer available.
If no seal fluid separator or discharge silencer (SI) being installed:● Seal hermetically the discharge connection (OUT) with a blind flange and o-ring and all otherapertures with the caps provided with the machine, or with adhesive tape if the caps are nolonger available.
Applicable for all above:● Wrap the machine in a VCI film (Vapor Corrosion Inhibitor).
● Store the machine indoors, in a dry place, away from dust and vibrations and if possible, in
original packaging, preferably at temperatures between 0 ... 40°C.
● Every 6 months of storage, remove the protective cover of the transmission belts and turn thetransmission pulley of the high pressure stage (HPS) a quarter turn in the direction indicatedby the arrow on the motor, to ensure that the static load of the rotors does not remain constantly applied to the same location on the bearings and shaft sleeves.
● Repeat the procedure of conservation after 12 months of immobilization.

When putting the machine back into service after storage:● Make sure that all remains of adhesive tape are removed from the ports.
● Make sure that the blind flange at the discharge connection (OUT) is removed.
Direct cooling version:● Reconnect the water supply line to the machine.
Radiator cooling version:● Check the level of water/glycol cooling liquid, refill if necessary.

Connecting Lines / Pipes
WARNING
Unprotected connection.
Risk of severe injury!
● Do not put hand or fingers in the connection.
● Remove all protective covers before installation.
● Make sure that the connection lines cause no stress on the connections of the machine. Therefore, we recommend installing flexible lines on the suction and discharge connections.
● Make sure that the diameter of the connection lines over the entire length is at least as large as
the connections of the machine.
In case of long connection lines, it is recommended to use larger diameters to avoid a loss of efficiency. In this case, please contact your Busch representative.
● Make sure that the connection flanges are fitted with the appropriate gaskets.

5.2.1

If the machine is used as part of a vacuum system:● Busch recommends the installation of an isolation valve in order to prevent the machine fromturning backwards.
● Busch recommends the installation of an isolation valve in order to prevent the oil from flowing back to the vacuum system.
● Busch recommends the installation of an isolation valve in order to prevent the process gases
and debris flowing back to the vacuum system.
● Make sure that the connection lines cause no stress on the connections of the machine. Therefore, we recommend installing flexible lines on the suction and discharge connections.
Huckepack vacuum pumps are supplied with a loose-packed inlet screen (IS) and a fine screen (FNS)● Assemble both screens on the inlet connection (IN), to prevent foreign particles from entering into the machine.
If the machine is supplied with an inlet flange, both screens are already assembled in the flange.
● Remove the fine screen (FNS) after about 20 working hours (the inlet screen (IS) remains in place).
