Cast Iron Gear Pumps
The P197/P257 series is a series of high performance gear pumps.
This completely new design utilizing computer aided engineering has allowed Permco to develop a state of the art external gear pump for heavy duty, high performance mobile applications.
Utilizing specialized sleeve bearing technology, gear journals are supported via a hydro-dynamic film, thus allowing continuous working pressures up to 4500 psi (310 bar) dependent upon the series and the selected gear size.
At rated speeds up to 2400 rpm, the series is compatible with all mineral based hydraulic oils and some fire resistant fluids (water glycol and invert emulsions). Employing high strength iron for all pump body components and an all doweled construction, the P197/P257 is well suited for high pressure and high shock load applications.
