HYDRAULIC SCHEMATIC (ALL MODELS)
BI-DIRECTIONAL PUMPS
These pumps are driven by reversible motors and are primarily used to power double-acting cylinders in both
directions. Locking checks that hold the load in either direction are standard.
Table 1 – Hydraulic Oil Specifications
If the lift will be used at normal ambient temperatures, Presto-ECOA Lifts supplies the unit with Conoco
Super Hydraulic 32 oil. This may be replaced by any other good quality oil with 150 SSU at 100° F
and rust and oxidation inhibitors and anti-wear properties.
If the lift will be used at ambient temperatures below 0°F, use aircraft hydraulic oil. Use Type 15
aircraft hydraulic oil.
The following are equivalent to Conoco Super Hydraulic 32:
TYPE MANUFACTURER
AW32 ................................. CITGO
DTE 24 ............................. EXXON/MOBIL
NUTO H32 ........................ EXXON/MOBIL
AMOCO AW32 .................. CHEVRON (AMOCO CO.)
CAUTION!
It is very important to keep the hydraulic oil free of dirt,
dust, metal chips, water, and other contamination.
Most of the problems with hydraulic systems are caused by contamination in the oil.
