Concentric AB-FERRA F12 SERIES-2011-06 2 DESIGNED FOR HEAVY DUTY The FERRA F12 pump is a rugged two-piece pump available with displacements from 16 to 41 cc/rev and pressures up to 276 bar (4000 psi up to 30 cc/ rev). FERRA pumps feature cast iron construction, resulting in a compact unit that is extremely robust across a broad temperature range, while also o ering increased power density and good installation characteristics compared with conventional designs. Both the housing and the front cover are of cast iron, which has made it possible to eliminate the rear cover, integrate the gearing into the housing and make the whole unit more compact.

The FERRA pump’s gear pro le is of an advanced design optimized for reduced pulsation and high power density in relation to the unit’s relatively small package size. Extensive testing has demonstrated that the FERRA pump matches or exceeds competitors’ products in a smaller package and o ers signi cantly better performance at low speeds. Both bench tests and in-vehicle tests have shown that the design is highly suitable for high- ow implement and steering circuits and fan drive applications. quality products for mechanical & fluid power ~ jbj Techniques Limited, www.jbj.co.uk UK distributor for Concentric Hydraulics
