CASAPPA Hydraulic Gear Motors KM40.133B0-34S8-LOF/ F-N

CASAPPA KM40.133B0-34S8-LOF/OF-N is a KAPPA 40 external gear motor built by Casappa in a two-piece cast-iron construction, with the housing and the mounting flange in cast iron and the gear pair carried on sleeve bearings between pressure-balanced thrust plates. Its 134.03 cm³/rev (8.18 in³/rev) gear set runs from 300 to 2,500 r/min and is rated 200 bar (2,900 psi) continuous operating pressure, 220 bar (3,190 psi) system pressure and 240 bar (3,480 psi) peak — the top of the KAPPA 40 displacement range, where the rigid cast-iron structure is what holds volumetric efficiency as pressure and temperature rise. The unit is reversible with an internal drain (code B), carries the SAE "C" 2–4 hole mounting flange and the SAE "C" straight drive shaft, and takes its inlet and outlet on the side through SAE straight-thread ports, which lets it replace an existing motor in a group 4 envelope without modifying the driveline.

| CASAPPA KM40.133B0-34S8-LOF/OF-N Applications

The motor is engineered for continuous-rotation drives in mobile and industrial hydraulic circuits that sit at the heavy end of the gear-motor range. Casappa positions the KAPPA 40 range on building and construction machinery, mining equipment, material handling, agriculture, forestry, turf care and mowers, and fan-drive systems — converting hydraulic flow into rotary torque and holding it under sustained load, high duty cycles and demanding ambient conditions. Its cast-iron body and flange, its SAE standard mounting interface and its ability to accept fire-resistant fluids let the same unit be fitted to machinery working outdoors, in dust and in high-temperature circuits.

1. Overview of CASAPPA KM40.133B0-34S8-LOF/OF-N

CASAPPA KM40.133B0-34S8-LOF/OF-N is a KAPPA 40 external gear motor. Casappa builds the KAPPA 40 range as a rigid, compact two-piece cast-iron assembly — shaft seals, seal, thrust plate, body, gear and mounting flange are the six elements Casappa identifies in the KAPPA 40 section drawing — so the gear pair stays square under load and the unit keeps its volumetric efficiency as pressure rises and as it wears.

The 134.03 cm³/rev (8.18 in³/rev) gear set is rated 200 bar continuous, 220 bar system and 240 bar peak, and turns between 300 and 2,500 r/min. Casappa quotes approximate efficiencies for KAPPA 40 motors of 0.92 volumetric, 0.85 hydro-mechanical and 0.78 overall.

Its function in a circuit is the reverse of a pump: it converts pressurised oil flow into rotary torque and speed at the output shaft. This unit is reversible with an internal drain, so it accepts either direction of rotation; it carries the SAE "C" 2–4 hole mounting flange and the SAE "C" straight drive shaft, and its inlet and outlet are on the side in SAE straight-thread ports. The same KAPPA 40 motor is available across the series with European or SAE flanges, four drive shafts, and split-flange, GAS or SAE threaded ports.

3. Motor Installation Specifications CASAPPA KM40.133B0-34S8-LOF/OF-N

The Casappa KAPPA 40 motor ordering code is a 12-position string: each position selects one characteristic of the unit, and reading it is the fastest way to confirm that a motor will fit an existing installation. Positions 1 to 8 define the unit itself; positions 9 to 12 define the drain port, the shaft-seal option, the body design and the painting.

5. Advantages of CASAPPA KM40.133B0-34S8-LOF/OF-N

Two-piece cast-iron body and mounting flange. Casappa builds the KAPPA 40 range as cast-iron pumps and motors in two pieces — shaft seals, seal, thrust plate, body, gear and mounting flange make up the assembly, and the rigidity of that structure is what holds reliability and volumetric efficiency at high working pressures.

Rigid and compact structure. Casappa presents the KAPPA 40 range as a rigid, compact design that makes it possible to incorporate a number of functions in a limited space.

Reversible with internal drain. One part number covers both directions of rotation, which reduces the number of spares a machine fleet has to carry and removes an external drain line from the installation.

High pressure capability for the displacement class. 200 bar continuous, 220 bar system and 240 bar peak — still 240 bar peak at 134 cm³/rev, where gear motors of this size commonly lose pressure rating.

Published efficiencies. Casappa quotes approximate values of 0.92 volumetric, 0.85 hydro-mechanical and 0.78 overall for KAPPA 40 motors.

Accepts fire-resistant fluids. The seal table lists HFA oil-in-water emulsion, HFB water-in-oil emulsion, HFC water-glycol and HFD phosphate ester alongside standard ISO/DIN mineral oils.

European and SAE standard interfaces. The catalogue lists European and SAE standard mounting flanges with threaded or split-flange ports, so the same motor can be matched to an existing driveline.

SAE J744 flange and SAE "C" shaft. The S8 flange conforms to SAE J744 and the 34 shaft is the SAE "C" straight shaft, the interface that mobile machinery is already built around.

Range features as published by Casappa. The catalogue presents the range on solid and compact design, high efficiency at high temperature and low emission of noise.

Wide displacement coverage. The KAPPA 40 range runs from 61.43 cm³/rev (3.75 in³/rev) to 150.99 cm³/rev (9.20 in³/rev), so a machine fleet can standardise on one motor family.

| Brand Replacement

HENGYUHANG supplies a replacement for the CASAPPA KAPPA 40 gear motor series, including KM40.133B0-34S8-LOF/OF-N and the rest of the KM 40 size range from KM 40•63 to KM 40•151. The replacement is built to the same dimensional envelope and the same international standard interfaces — European and SAE mounting flanges, the same drive shaft families, and split-flange, GAS or SAE threaded ports — so that a machine originally fitted with a Casappa KAPPA 40 motor can be returned to service without modifying the driveline, the mounting or the pipework.

Replacement units are supplied to Casappa's published interface and dimension data for the KAPPA 40 range. The ordering code of the original motor is the reference used to confirm fitment, so please quote the complete original order number when enquiring.

| Applications of CASAPPA KM40.133B0-34S8-LOF/OF-N

Typical applications of the KAPPA 40 gear motor family:

  • Building and construction — drives and auxiliary circuits on construction machinery, roller and drum drives, track and wheel drives on compact machines

  • Mining — heavy-duty drives on mining equipment and mineral processing machinery

  • Material handling — drive and positioning functions on handling equipment, winches and reel drives

  • Agriculture — drives for headers, conveyors, agitators and implement functions on tractors, balers, harvesters and sprayers

  • Forestry — feed, conveyor and attachment drives on forestry machinery

  • Turf care and mowers — mower deck and reel drives on grounds-care equipment

  • Fan drive — engine cooling fan drives and hydraulic fan circuits

In these machines the motor drives loads that turn continuously at moderate speed, and is expected to hold torque under sustained load, high duty cycles and demanding ambient conditions. The cast-iron body, the internal drain that makes it reversible and the ability to run on fire-resistant fluids let it work in circuits where the direction of rotation is set by the duty cycle and where oil temperature and contamination are the deciding factors.
