Continental Hydraulics PVX Series Service Manual

CAUTION – Before performing any service
operation on any PVX Vane Pump, be sure
that all pressure has been relieved from
BOTH SIDES of the system.
CAUTION – Before performing any service
operation on any PVX Vane Pump, discon-
nect or lock off power supply.
CAUTION – Before manually actuating any
PVX Vane Pump, be sure that any resulting
machine function will not endanger persons
or equipment.
PRODUCT IDENTIFICATION
Each PVX Vane Pump has a Model Code stamped
on its nameplate. See Figure 1 for the location of the
Model Code.
This Service Booklet applies to products with
Ordering Codes like the sample in Figure 2.

SYSTEM REQUIREMENTS
FLUID RECOMMENDATIONS - Use premium quality
hydraulic fluids which fall within the viscosity ranges
listed below, at normal operating temperature. Fluids
containing anti-wear additives are not required, but
recommended and when used may extend the life of
system components.

Model
PVX-8
PVX-11/15
PVX-20/29/36
PVX-46/60/75
FLUID TEMPERATURE - Pump reservoir (bulk) fluid
temperature should not exceed 130° F. (54° C.).
Always select fluid for optimum viscosity at operating
temperature. In no instance should fluid temperature
exceed 160° F. (71° C.).
FILTRATION - For increased component life, fluid
contamination should not exceed 16/13 per ISO/DIS
4406 "Solid Particulate Contamination Code".
CRITICAL SHAFT ALIGNMENT - PROPER SHAFT
ALIGNMENT IS NECESSARY TO MINIMIZE
EQUIPMENT NOISE, VIBRATION AND SHAFT SEAL
WEAR. Align to less than .006 inches (0.152 mm), as
shown in Figures 3 and 4.
Two precision dial indicators must be used to insure
proper alignment in vertical, horizontal, and parallel
planes.

Shaft
Coupling halves can be either engaged or disen-
gaged. If disengaged, the outside diameter of the
pump coupling must be smooth and machined true in
respect to the coupling bore.
Proper alignment is achieved when neither indicator
varies more than 0.006 inch (0.152 mm) during one
complete shaft revolution.
