CASAPPA KP30.34D-83E3-LED/EB-N 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 34.56 cm³/rev (2.11 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 European 1:8 tapered drive shaft (code 83), the European E3 mounting flange and side-positioned European flanged ports (ED/EB), it runs from 350 to 3,000 r/min, is rated 250 bar (3,625 psi) continuous pressure, 270 bar (3,915 psi) system pressure and 290 bar (4,205 psi) peak in the standard CSC body design, and moves up to 103.7 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 KP30.34D-83E3-LED/EB-N 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 — 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. European, SAE and ISO 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 KP30.34D-83E3-LED/EB-N
CASAPPA KP30.34D-83E3-LED/EB-N 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 standard CSC body design the 34.56 cm³/rev gear set is rated 250 bar continuous, 270 bar system pressure and 290 bar peak, and turns between 350 and 3,000 r/min.
Its function in a circuit is to draw oil from the reservoir and convert drive-shaft rotation into pressurised flow. This unit carries the European E3 mounting flange, the European 1:8 tapered drive shaft (code 83) and European flanged four-bolt side ports — inlet ED (27 mm nominal), outlet EB (19 mm nominal). The same range can be ordered with European, SAE and ISO mounting flanges, nine drive-shaft options and threaded, split-flange or flanged ports, so one pump family covers a wide spread of existing installations.

The Casappa KAPPA 30 ordering code is a 12-position string: each position selects one characteristic of the unit, and reading it is the fastest way to check that a pump 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.

External gear pump · KAPPA 30 series · 250 bar continuous · 34.56 cm³/rev
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.
250 bar continuous, 270 bar system pressure and 290 bar peak in the standard CSC body design; the same displacement is available with the Compact and High performance body designs when the installation calls for a different pressure/flow trade-off.
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.
KAPPA pumps can be ordered with integrated valve functions, which removes external plumbing from the circuit.
The E3 flange and the 1:8 tapered drive shaft match the mounting and the coupling European mobile machinery is already built for, and the ED/EB four-bolt flanged ports take standard European flange fittings.
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.
KAPPA is the range Casappa positions for applications where noise, contamination, non-flammable fluids and envelope size are the deciding factors.
Every size below is a valid position 1 in the KAPPA 30 pump ordering code. Pressures are the ratings for unidirectional pumps with side ports and the CSC / CSL Standard body design; reversible pumps are limited to a maximum of 250 bar, except the sizes whose rated value is lower.

HENGYUHANG supplies a replacement for the CASAPPA KAPPA 30 gear pump series, including KP30.34D-83E3-LED/EB-N and the rest of the KP 30 size range from KP 30•22 to KP 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 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. The ordering code of the original pump is the reference used to confirm fitment, so please quote the complete original order number when enquiring.
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.
