3500 PSI Fixed Displacement Mobile Vane Pumps

Thru-Drive 35VQHT*S
Single 35VQH Double 3525VQH
2 EATON Vickers VQH Series V-PUVN-MC001-E February 2004
Single and Thru-
Drive Pumps
VQH Series fixed displace-
ment single and double vane
pumps employ a new rotor
design that enhances pres-
sure capability and efficiency
over the 20th design VQ
pumps. VQH cartridge kits
are interchangeable with
those of VQ series. In order
to accommodate high pres-
sure requirements, the VQH
pump housing is upgraded to
ductile iron. The VQH installa-
tion dimensions are exactly
the same as VQ pumps.
Available Pump Frame
sizes are:
Single and Thru-Drive pumps:
25, 35, and 45
Double Pumps:
2520, 3520, 3525, 4520,
4525 and 4535
For installation dimensions,
please refer to VQ pump sec-
tion in Cat. 353 “Vane Pump
and Motor Design Guide for
Mobile Equipment.”
