This pump features adjustable volume in a
compact design. Adjustment from 4-12 in³
per turn is easily accomplished from the
outside. A ball bearing and two thrust
bearings provide smooth operation and
long life. A lock valve installed on the
back of the helm pump prevents rudder
feedback and also allows installation of
multiple control stations. The pump is
normally supplied in its die cast bronze
finish. It can, however, be ordered in a
black epoxy finish.
Materials: Housing and rotor are die-cast
silicon bronze. Pistons and pintol
are hardened and ground steel.
Pump shaft and hardware are
stainless steel.
