The vacuum/pressure blowers pump should be assembled and installed using the following procedure:
1) Assemble the vacuum/pressure blowers pump horizontally with its feet facing downwards.
2) Bolt the vacuum/pressure blowers pump via passing screws and nuts in the appropriate slots or holes provided in the feet.
3-P/PM) To install the BLW vacuum/pressure blowers pump version .../P and PM, it is necessary to install / secure a driven
pulley on the shaft; the driven pulley must be installed as close as possible to the drive element, trying to limit the length of the
free section (see diagram below). Never transfer axial loads. Then connect the driven pulley to the driving pulley with the correct
length of driving belts.
The number and type of belts must be calculated based on the power to be transmitted to the BLW vacuum/pressure blowers
pump.
When this operation has been completed, the necessary guard must be installed to isolate the driving parts (pulleys and belts) and
prevent access to them by the operators.
The tension of the belts must be such that, with the bands pulled, they can still be stretched by approximately 2 cm.
A higher belt tension can cause the shaft to break
- The best tension is the lower one where the belt doesn't slide under max loading condition.
- Check frequently the tension during first 24/48 hours of running phase.
- The over-tension reduces the life of belt and bearing.
- Keep belts free from any material which may cause sliding.
- Check the transmission periodically. Set it when sliding.
To check the tension on a normal transmission, proceed as follows:
- Measure the length of free stretch, t.
- In the middle of the free stretch of the belt (t) apply a force (perpendicular to the free stretch) sufficient to bend the belt 1.6 mm per
100 mm in length of the free stretch. For example, the bending of a free stretch of 1000 mm is 16 mm.
- Compare the force you have applied and measured through a instrument with data stated under our table. If the force is included
between "minimum force" data, it means that the belt is not enough stretched. If the force exceeds "max force" data, it means that
the belt is too stretched.
However, a new transmission can be initially tensioned to twice the value of "min strength" to allow normal adjustment of tension
during operation.

Do not use the BLW pump with a direction of rotation other than that indicated by the arrow.
3 /H) To install the BLW /H vacuum/pressure blowers pump, it is necessary to install a hydraulic motor on the support located at the front
(if not supplied already installed), secure it using appropriate screws and connect the hydraulic pump pipes to the hydraulic motor.
4) Then connect the intake/compression pipe of the tank car to the BLW vacuum/pressure blowers pump tightening it to the adjustable
elbow using metal clamping bands in relation to the diameter of the pipe.
