CASAPPA Hydraulic Gear Motor KM30.34

1. Overview of CASAPPA KM30.34R0-83E3-LOD/OD-N

CASAPPA KM30.34R0-83E3-LOD/OD-N is a KAPPA 30 (group 3) external gear motor. Casappa builds the KAPPA pump and motor units around a housing and a mounting flange in cast iron of superior mechanical specification; the gear pair runs on sleeve bearings between pressure-balanced thrust plates, so the assembly stays rigid and keeps its volumetric efficiency as pressure rises and as the unit wears. The 34.56 cm³/rev gear set is rated 260 bar continuous, 280 bar intermittent and 300 bar peak (reversible units 15 % lower: 221 / 238 / 255 bar) and turns between 350 and 3,000 r/min.

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 a rear external drain, so it can be driven in either direction once the case drain line is connected; it carries the European E3 mounting flange, a European 1:8 tapered drive shaft and side-positioned SAE straight-thread ports, and it can be ordered across the same range with SAE, European and ISO flanges, several shaft types and screw or flanged ports.

3. Motor Installation Specifications CASAPPA KM30.34R0-83E3-LOD/OD-N

The Casappa KAPPA 30 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.

Code structure — official example: KP 30•27 R 0 - 04 S3 - L OF/OD - N - OA - C4 - CSC - VNR01

Reading your code: KM30.34R0-83E3-LOD/OD-N

Note on position 7 — OD/OD. The OD letter pair belongs to the SAE straight-thread (ODT) port family, but the officially listed KM 30 code for this displacement is OD/OF (KAPPA 30 Compact ordering table, DCAT060-ID02, p. 53; KAPPA 30 single-motor ordering table, p. 107). The same code string is printed in the port-position group as -L OD/OD-, i.e. position 6 (L, side) immediately followed by position 7. Please confirm the port pair against your original Casappa drawing, nameplate or supplier datasheet before publishing: if the original unit is OD/OF, the published model number changes by one letter.

Note on positions 9 to 12. The published number stops at position 8, so no drain-port code, shaft-seal option, body design or painting is specified: the case drain port then defaults to the standard GAS straight thread (BSPP). If the original Casappa number carries a tail such as -C1, -C4, -CSC, -OA or -VNR01, the published model number should carry the same tail.

5. Advantages of CASAPPA KM30.34R0-83E3-LOD/OD-N

Cast-iron housing and mounting flange. KAPPA units are built around cast-iron body and flange components, and the rigidity of that assembly is what holds reliability and high volumetric efficiency at high operating pressures.

High pressure capability. 260 bar continuous, 280 bar intermittent and 300 bar peak in the uni-directional version; this reversible unit is rated 221 / 238 / 255 bar, and the case drain keeps the rating stable in both directions of rotation.

Reversible with rear external drain. One part number covers both directions of rotation, which reduces the number of spares a machine fleet has to carry.

High efficiency at high temperature. Casappa specifies the KAPPA range for high efficiency at high temperature — the oil film in a gear motor thins as the circuit heats up, and the cast-iron structure limits the loss of volumetric efficiency.

Long service life. Pressure-balanced thrust plates compensate for wear, and Casappa rates the range for exceptional working life expectancy.

Low noise emission. The gear-motor design keeps running noise low, which matters on fan-drive, turf-care and municipal machinery that works close to the operator.

European standard interface. The E3 flange and the 1:8 tapered drive shaft match the mounting and the coupling that European mobile machinery is already built for.

Wide combination choice. SAE, European and ISO mounting flanges, several drive shafts and screw or flanged ports let the same motor be matched to an existing driveline.

Suited where fluids and size are critical. KAPPA is the range Casappa positions for applications where noise, contamination, non-flammable fluids and envelope size are the deciding factors.

6.1 The KM 30 range — same series, all displacements

Every size below is a valid position 1 in the KAPPA 30 motor ordering code. Pressure figures are the official gear-motor ratings for uni-directional motors; reversible motors are rated 15 % lower.

The current KAPPA 30 Compact range extends the same motor family with KM 30•22 (21.99 cm³/rev), KM 30•31 (30.63 cm³/rev), KM 30•41 (41.62 cm³/rev) and KM 30•46 (46.34 cm³/rev). The matching pump range is KP 30 with the same displacements.

7. Brand Replacement

HENGYUHANG supplies a replacement for the CASAPPA KAPPA 30 gear motor series, including KM30.34R0-83E3-LOD/OD-N and the rest of the KM 30 size range from KM 30•22 to KM 30•73. The replacement is built to the same group 3 dimensional envelope and the same international standard interfaces — European, SAE and ISO mounting flanges, the same drive shaft families, and screw or flanged ports — so that a machine originally fitted with a Casappa KAPPA 30 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 30 group. The ordering code of the original motor is the reference used to confirm fitment, so please quote the complete original order number when enquiring.

8. Applications of CASAPPA KM30.34R0-83E3-LOD/OD-N

Typical applications of the KAPPA 30 gear motor family:

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

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

Forestry — feed, conveyor and attachment drives on forestry machinery

Fan drive — engine cooling fan drives and hydraulic fan circuits

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

Industrial hydraulics — conveyors, mixers, presses, machine tools and plastic injection moulding machines

Special vehicles — municipal vehicles, aerial work platforms and cleaning vehicles

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 and the case drain that make it reversible also allow it to be used in circuits where the direction of rotation is set by the duty cycle rather than fixed at installation.
