CASAPPA KP30.24D0-A8K9-LMD/MB-N-HSC, KP30.29DO-A8K9-LMD/MB-N, and KP30.43-A8K9-LMD/MC are KAPPA 30 cast-iron external gear pumps — the group 3 size of Casappa's two-piece cast-iron range, covering geometric displacements of 24.03 cm³/rev (1.47 in³/rev), 29.06 cm³/rev (1.77 in³/rev), and 43.98 cm³/rev (2.68 in³/rev). Body and mounting flange are cast iron of superior mechanical specification, and the solid, compact two-piece assembly carries a precision external gear pair on sleeve bearings between pressure-balanced thrust plates that compensate for wear and hold volumetric efficiency as pressure rises. Configured with the SAE "B" spline drive shaft for the K9 flange (code A8), the SAE "B" two-hole mounting flange (K9) and side-positioned SAE flanged J518 ports — inlet MD (1-1/4") with outlet MB (1/2") on KP30.24 and KP30.29, and inlet MD (1-1/4") with outlet MC (1") on KP30.43 — these clockwise-rotation units (D / DO) are built without an outboard bearing (0): they run from 350 to 3,000 r/min, are rated up to 280 bar (4,060 psi) relief-valve setting and 300 bar (4,350 psi) peak on KP30.24, 270 bar (3,915 psi) relief-valve setting and 290 bar (4,205 psi) peak on KP30.29, and 250 bar (3,625 psi) relief-valve setting and 270 bar (3,915 psi) peak on KP30.43, moving up to 72.1 l/min, 87.2 l/min, and 131.9 l/min of oil at maximum speed — high pressure and high flow in a reduced envelope, with low noise emission and the long working life the cast-iron KAPPA construction is specified for.
| CASAPPA KP30 Series Applications
The pump is engineered to feed continuous-duty hydraulic circuits on mobile and industrial machinery. It is used on building and construction equipment, material handling machinery, forestry machines and fan drives, and across the wider KAPPA application range on agricultural implements, cranes, winches, mixers, presses and machine tools — drawing oil from the reservoir and converting drive-shaft rotation into pressurised flow for cylinders, motors and valve blocks, and holding that flow under sustained load, high duty cycles and demanding ambient conditions. SAE and European standard mounting flanges, drive shafts and ports let the unit be fitted to existing machinery without modifying the driveline, the mounting or the pipework.

| Overview of CASAPPA Cast Iron External Hydraulic Gear Pumps (KP30.24 / KP30.29 / KP30.43)
CASAPPA KP30.24D0-A8K9-LMD/MB-N-HSC, KP30.29DO-A8K9-LMD/MB-N, and KP30.43-A8K9-LMD/MC are KAPPA 30 external gear pumps. Casappa builds the KAPPA range around a body and a mounting flange in cast iron of superior mechanical specification, and the KAPPA 30 is a solid, compact two-piece construction that allows several functions to be packed into a reduced space. Inside, the external 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. In the HSC Compact and standard body designs, the 24.03 cm³/rev, 29.06 cm³/rev, and 43.98 cm³/rev gear sets operate between 350 and 3,000 r/min under continuous high-pressure duty cycles.
Their function in a circuit is to draw oil from the reservoir and convert drive-shaft rotation into pressurised flow. These units carry the SAE "B" two-hole mounting flange (code K9), the SAE "B" 13-tooth spline drive shaft made for that flange (code A8) and side-positioned SAE flanged J518 ports, so inlet and outlet leave the pump on the side faces — the layout used where the pipework runs alongside the pump and the rear face stays clear. Position 2 carries D / DO: the pump is a clockwise-rotation unit, looking at the drive shaft. The 0 that follows it is the outboard-bearing position: these pumps are built without an outboard bearing, the standard configuration of the range. The same range can be ordered with European, SAE and ISO mounting flanges, nine drive-shaft options, four port positions and threaded, split-flange or flanged ports, so one pump family covers a wide spread of existing installations.

The KAPPA range is built around a body and a mounting flange in cast iron of superior mechanical specification, and the rigidity of that assembly is what holds reliability and high volumetric efficiency at high operating pressures.
Up to 280 bar (4,060 psi) relief-valve setting and 300 bar (4,350 psi) peak at 3,000 r/min on KP30.24, with high performance levels available across the displacement group.
The KAPPA 30 packs several functions into a reduced space, which matters where the pump has to fit inside an existing housing or a tight driveline envelope.
The external gear design keeps running noise low, which is a requirement on fan drives, municipal machinery and equipment working close to the operator.
Pressure-balanced thrust plates compensate for wear, so the pump keeps its flow as the unit ages.
As the circuit oil heats up and the film thins, the cast-iron structure limits the loss of volumetric efficiency — the property Casappa specifies the KAPPA range for.
24.03 cm³/rev, 29.06 cm³/rev, and 43.98 cm³/rev let machine builders fine-tune circuit flow without stepping outside the standard Group 3 mounting footprint.
The code states D (clockwise) and 0 (without outboard bearing), so the drive direction and the shaft support arrangement are fixed at order stage rather than left to installation.
The K9 two-hole SAE "B" flange and the A8 SAE "B" 13-tooth spline shaft match the SAE mounting and coupling that mobile machinery is built for, and the side-positioned SAE flanged J518 ports take standard split-flange fittings.
KAPPA pumps can be ordered with integrated valve functions, which removes external plumbing from the circuit.
European, SAE and ISO mounting flanges, nine drive shafts, four port positions and threaded, split-flange or flanged ports let the same pump family be matched to an existing driveline, mounting and pipework.
KAPPA is the range Casappa positions for applications where noise, contamination, non-flammable fluids and envelope size are the deciding factors.

HENGYUHANG supplies a replacement for the CASAPPA KAPPA 30 gear pump series, including KP30.24D0-A8K9-LMD/MB-N-HSC, KP30.29DO-A8K9-LMD/MB-N, and KP30.43-A8K9-LMD/MC, as well as the rest of the KP 30 size range from KP 30•19,5 to KP 30•82, in pump and gear-motor form. 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 threaded, split-flange or flanged ports — so a machine originally fitted with a Casappa KAPPA 30 pump 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. Fitment is decided by the ordering code of the original pump, so please quote the complete original order number when enquiring.
8. Applications of CASAPPA KP30 Series
Typical applications of the KAPPA 30 gear pump family:
Building and construction — supply pump on compact machines, excavators and loaders, roller and drum drives, auxiliary circuits
Material handling — lifting, tilting and positioning circuits on handling equipment, cranes and aerial platforms
Forestry — feed, conveyor, saw and attachment drives on forestry machinery
Fan drive — engine cooling fan drives and hydraulic fan circuits
Agriculture — supply and implement circuits on tractors, balers, harvesters, sprayers and seeders
Industrial hydraulics — presses, mixers, machine tools and plastic injection moulding machines
Special vehicles — municipal vehicles, cleaning vehicles and truck-mounted equipment
In these machines the pump feeds loads that run continuously at moderate circuit pressure, and is expected to hold flow under sustained load, high duty cycles and demanding ambient conditions. The cast-iron body, the sleeve-bearing gear pair and the pressure-balanced thrust plates are what let the unit keep its volumetric efficiency as circuit pressure and oil temperature rise.
