• In order to avoid accidental suction of liquids inside the pump,
install a primary (pos. 1) and a secondary flow shutoffs (pos. 2). If
necessary, install also a suction filter (pos. 3) to protect from solids
infiltration.
• The exhaust silencer is designed to reduce the noise level and to
separate the oil mist coming out from the pump outlet port. The
separator must be periodically drained from oil and condensate
accumulated in the separator during the normal pump functioning.
• The diameter of the vacuum/pressure line pipes must be properly
dimensioned to the pump flow and, in any case, larger than the
diameter of the ports (Ø100 is recommended).
• The pipes weight must not solicit the body of the pump. Use high
temperature resistant rubber connections.
• Before mounting the vacuum line to the pump, remove the port
protections. Pipes and all line components must be clean.
• Avoid restrictions and tight curves as much as possible if not
strictly necessary.
• Exhaust pipes can reach high temperatures. Hence, they must be
properly isolated.
• Max. pressure safety valve on delivery: mount it close to the pump.
The valve flow must prevent the PN130 - PN140 - PN155 from
exceeding the absolute operating pressure (see par. “Usage
limitations”) or, in any case, the maximum pressure allowed by the
system. Do not apply gate valves on the line.
• Over-pressure safety relief valve (pos. 6): to apply if necessary to
limit the vacuum rate in the system.
4.4. Pump mounting - Drive connection
A) Cardan shaft drive
• Use telescopic cardan shafts.
Fig. 4.1
• In order to achieve a uniform motion of the driven shaft, the
following requirements must be met (see Fig. 4.1):
- Equal working angle α and α1 of both couplings.
- The internal fork joints must be coplanar.
- Both driven and driving shafts must be coplanar.
• It is also recommended working with limited articulated joint angles
(max. 15°) and disengaging the transmission for those operations
requiring great angles (steering or lifting).
Follow the rotation direction as indicated on the
front flange. Follow the instructions of the cardan
shaft’s manufacturer.
• Use the protection that comes with the pump shaft.
Use the cardan protection supplied with the
pump. The pump installation must fulfil the
current EC injury prevention specifications.
B) Belt drive
Fig. 4.2
• Install a suitable pulley on the smooth shaft as close as possible
to the pump: L max 35 mm.
• Apply an adequate belt tension (see manufacturer’s data). T Max
3000N.
• Do not use driven or driving pulleys with a pitch diameter inferior
to 180 mm. Small pulleys require a high belt tension which may cause
premature wear to the bearing or transmission troubleshooting.
• If the pump PN155 is run through a belt drive, its working pressure
must not exceed 1.5 abs. bars to prevent it from absorbing a power
requiring an excessive belt tension. There is no limit to the operation in
vacuum.
Attention: If the pump PN155 is run through a belt
drive, its working pressure must not exceed 1.5
abs.
