CASAPPA Replacements
Casappa Hydraulic Gear Pump KP30.29D
CASAPPA KP30.29DO-A8K9-LMD/MB-N-HSC is a KAPPA 30 cast-iron external gear pump — the group 3 size of Casappa's two-piece cast-iron range, with a geometric displacement of 29.06 cm³/rev (1.77 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 here 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, outlet MB — it is a clockwise-rotation unit (D) built without an outboard bearing (0): it runs from 350 to 3,000 r/min, is rated 270 bar (3,915 psi) relief-valve setting and 290 bar (4,205 psi) peak in the Compact HSC body design, and moves up to 87.2 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 KP30.29DO-A8K9-LMD/MB-N-HSC 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 KP30.29DO-A8K9-LMD/MB-N-HSC
CASAPPA KP30.29DO-A8K9-LMD/MB-N-HSC is a KAPPA 30 external gear pump. 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 body design the 29.06 cm³/rev gear set is rated 270 bar (3,915 psi) relief-valve setting and 290 bar (4,205 psi) peak, and turns between 350 and 3,000 r/min; the high-performance build of the same size takes the rating to 300 / 320 bar (4,350 / 4,640 psi).
Its function in a circuit is to draw oil from the reservoir and convert drive-shaft rotation into pressurised flow. This unit carries 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: the pump is a clockwise-rotation unit, looking at the drive shaft. The 0 that follows it is the outboard-bearing position: this pump is 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.

Advantages
Cast-iron body and mounting flange
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.
High pressure from a compact body
270 bar (3,915 psi) relief-valve setting and 290 bar (4,205 psi) peak at 3,000 r/min, with the 300 / 320 bar (4,350 / 4,640 psi) high-performance level available in the same size.
Solid, compact two-piece construction
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.
Low noise emission
The external gear design keeps running noise low, which is a requirement on fan drives, municipal machinery and equipment working close to the operator.
Exceptional working life expectancy
Pressure-balanced thrust plates compensate for wear, so the pump keeps its flow as the unit ages.
High efficiency at high temperature
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.
Mid-range displacement on the group 3 envelope
29.06 cm³/rev (1.77 in³/rev) sits between the •27 and •31 sizes, so a machine can be brought back to its original flow without stepping up to a larger pump body.
Explicit rotation and outboard-bearing positions
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.
SAE interface
The K9 two-hole SAE "B" flange and the A8 SAE "B" 13-tooth spline shaft match the SAE mounting and coupling that North-American mobile machinery is already built for, and the side-positioned SAE flanged J518 ports take standard split-flange fittings.
Available with built-in valves
KAPPA pumps can be ordered with integrated valve functions, which removes external plumbing from the circuit.
Wide combination choice
European, SAE and ISO mounting flanges, nine drive shafts, four port positions and threaded, split-flange or flanged ports let the same pump be matched to an existing driveline, mounting and pipework.
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.

Brand Replacement
HENGYUHANG supplies a replacement for the CASAPPA KAPPA 30 gear pump series, including KP30.29DO-A8K9-LMD/MB-N-HSC and 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.
Applications
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.
