5. PUMP COMPONENTS

The pump assembly comprises:

A steel body with an hardened and lapped piston.

The pneumatic command assembly consisting of an aluminium cylinder wherein a piston operates with an oil

resistant rubber seal. A 3-way pneumatic control device: line-cylinder-exhaust is required.

A double spring ensuring the returning of the piston to its start position. The impulse time shall be sufficient to

pressurise the system and the pause, between one cycle and the next, shall allow complete release. The expansion

of the flexible tubing used in the system will reduce the potential delivery.

WARNING: The unit can only be opened and repaired by authorized Dropsa personnel.

6.1 UNPACKING.

Once a suitable location has been found to install the unit remove the pump from the packaging. Check the pump

has not been damaged during transportation or storage. No particular disposal procedures are necessary as

packaging materials are no dangerous for health or environment. However, packaging should be disposed of in

accordance with regulations that may be in force in your area or state.

6.2 INSTALLING THE PUMP

Allow sufficient space of at least 100 mm around the pump for ease of maintenance. Install at a suitable level for

refilling the oil reservoir. Do not install the pump neither in aggressive environments such as close to explosive

materials, nor on vibrating shelves.

No pump assembly operations are envisaged.

Check carefully the integrity of the reservoir as any denting could impede pressure disk travelling and

lubricant leakage.

Connect the pump to the compressed air system ensuring the maximum working pressure is not exceeded.

Fill the reservoir with lubricant avoiding presence of air under the pressure disk (it could impede the clutch of

the pump).

6.3 ADJUSTING THE PUMP

The only parameter which can be modified is that of pressure; to modify the value, increase or decrease the control

air pressure.

7.1 COMMISSIONING THE PUMP

♦ The unit must be utilised, opened and repaired ONLY by qualified personnel.

♦ The pump MUST NOT be utilized in particularly aggressive or explosive/inflammable environments if not

prepared for this purpose beforehand by the supplier.

♦ For correct fixing verify the distance between centres shown in the diagram in chapter 12.

♦ Use gloves and safety glasses as required in the lubrication oil safety chart.

♦ DO NOT use lubricants incompatible with NBR gaskets and seals; if in doubt consult our Engineering

Department, who will provide a chart with the details of recommended oils.

♦ DO NOT ignore health and safety regulations and observe all hygienic requirements.

♦ WARNING! All electrical components must be grounded. This refers both to electrical components and control

devices. As regard to this ensure that the ground cable is correctly connected. For reasons of safety the ground

cable must be approx. 100 mm longer than the phase cables. In the event of accidental detachment of the cable,

the ground terminal must be the last to be removed.
