Belt Driven Centrifugal Pumps
Frame Mount Advantages
Ace belt driven pumps are available in a variety of models which can be belt driven or direct coupled to a power source. The pumps are available in either clockwise or counterclockwise rotation. The standard bare shaft pumps are designed with a keyway for mounting a drive pulley or coupling.
Magnetic Clutch Driven Advantages
The integral magnetic clutch driven centrifugal pump design was first offered by Ace in 1982. These models enabled the operator to free the PTO shaft and hydraulic system for other uses. The 12 volt DC magnetic clutch is driven by a v-belt from the engine drive shaft. The clutch is idle until engaged by an on-off toggle switch located at the driver’s seat.
The direction of rotation is always determined WHEN FACING THE SHAFT. This rule applies for the pump shaft and the drive shaft. Ace Frame Mounted pumps are available in both clockwise (CW) and counterclockwise (CCW) rotation. Ace model numbers which include a “CW” have a clockwise rotation; all other models are counterclockwise rotation.
Typical Clutch Installation
Ace magnetic clutch driven frame mounted centrifugal pump models are available with counterclockwise (CCW) rotation and clockwise (CW) rotation. The direction of rotation is determined when facing the shaft. Sizes available are 1-1/4” x 1”, 1-1/2” x 1-1/4”, and 2” x 1-1/2”.
Ace offers the widest assortment of frame mounted centrifugal pumps for spray applications. These rugged, compact models offer mounting flexibility.
Maximum rigidity for tractor mounted pumps can be attained on a 1000 RPM PTO by placing one of the Ace splined pulleys on the tractor PTO shaft and driving a frame mounted pump with Poly-Flex belts as shown:
- FMK-30-2M Pulley has a pitch diameter of 6” (15.2 cm) and a 1-3/8” (34.9 cm) bore with 21 splines for mounting on a 1000 RPM tractor PTO. The pulley has a two groove design for use with two Poly Flex belts.
- FMK-30-4M Same as above with four groove design for driving two pumps.
- FMK-30-2M-175 Pulley has a pitch diameter of 6” (15.2 cm) and a 1-3/4” (44.5 cm) bore with 20 splines for mounting on a 1000 RPM tractor PTO. This pulley has a two groove design for use with two Poly Flex belts.
- FMK-30-4M-175 Same as above with four groove design for driving two pumps.
