The small package space is achieved by a number of design features including a new hydraulic
vane-type pump and two patented dog clutches replacing bulkier conventional clutch packs.
The compact packaging is achieved by using a number of innovative design features: A new compact hydraulic
vane-type pump, two patented dog clutches replacing bulkier conventional clutch packs, and a nested gear set.
The small package space is achieved by a number of innovative design features including a new hydraulic
vane-type pump which also contributes to improved efficiency, two, patented, dog clutches replacing bulkier conventional clutch packs, and an intelligently-nested gear set.
"We use a Parker Denison T6CCM dual
vane-type pump to power the cooling fans" Eckart explained.
The result is "hybrid" pumps, which combine a piston and
vane-type pump mounted on a single shaft, in a single housing, with a single inlet -- available in five different models.
The goal of our test was to determine if Sigma-Tek's piston pump beats conventional
vane-type pumps in output, especially at idle power settings.
Low-pressure pumps are usually
vane-type pumps. These pumps generally cost less to purchase but require extensive maintenance.
Vane-type pumps also require more horsepower than a PD pump.
