PUMP WITH PULLEY
The priming operation is the same as the one of the electric pumps. Use a V-shaped belt for connection to a motor. When calculating the pulley ratio between the motor and the pump, take into account that a
maximum 2,500 g/1' (rpm), measured at the pump shaft is allowed.
WARNING: protection of the external motor for pulley pumps is at the user's expense.

SAFETY OF ELECTRICAL PRODUCTS
The sale and installation of safe products is a matter involving professional ethics and seriousness towards customers.
Wholesalers and installers are unable to check the safety of a product themselves, as this practice would be both complicated and expensive. What can they do, therefore, to protect themselves against administrative and/or penal
liabilities?
Concentrate on the reliability and seriousness of the manufacturers, and resist the temptation to purchase low cost goods of uncertain origin. Do not settle for the CE mark only as this is a self-certification issued by the
manufacturer, and consequently unreliable if manufacturer is unreliable.
It is, therefore, important to check for the presence of a safety mark like the IMQ (www.imq.it)
Within the electrical sector, safety marks guarantee that:
the product has been tested by a competent, independent body, and acknowledged as conforming to the relative safety requirements before being launched on the market;
the production processes are checked continuously;
the certification body checks the products periodically in order to ascertain whether the level of quality has been maintained.
The safety mark is the main instrument which helps customers choose safe, reliable products at first glance. Moreover, the mark enables wholesalers, installers and end users to choose between safe and low quality products, thus
improving their image in the eyes of their own clients.
ROVER POMPE products have carried the IMQ mark since 1996, which clearly demonstrates the commitment the company has to ensuring the safety of its products, and spreading the knowledge of their safety in daily use.
Safety marks in brief...
Installers and retailers are considered liable for their work by law and are thus obliged to sell and install safe electrical materials which conform to the provisions set down by law. They can be charged with administrative and penal
sanctions for failing to do so.
Purchasing certified electrical products is the safest way of proving you have done all the necessary measures for ensuring safety.
The safety mark means that an independent body will control the product before it is sold on the market. The mark is issued by a third party and is not simply the manufacturer's self-certification, even though it is compulsory by
law.
The safety mark means that prototypes are checked and standard production is kept under control.
The sale and installation of certified products guarantees a company's professionalism. Anyone who uses certified products guarantees both their own safety and the safety of those working with them.
CE MARK
The CE mark is the manufacturer's declaration that a product satisfies all the legislative requirements of the European Community which can be applied to it. This mark has the function of assuring the public authorities in
European Union countries that a given product fully satisfies the legislative obligations in force at any time.
The CE mark does not replace the IMQ mark. CE marked goods may conform to the standards in force in Europe, whilst IMQ marked goods actually do conform, as they are checked by an independent, competent body. The
safety of the IMQ mark increases the value of a product, even those which carry the CE mark.
The CE mark is compulsory. Manufacturers attach it to a product, and no controls are carried out by third parties. All goods sold in Europe must carry this mark and it is attached either to the product, the packaging or the warranty.
All products must carry this mark, so consumers have no guarantee that the product is safe.
