Note: Continuous pressure de‑rates as displacement increases. Reversible‑rotation pumps have lower continuous pressure rating.
Key Features
- Two‑piece compact cast‑iron housing: High mechanical rigidity, strong shock resistance, keeps good volumetric efficiency under high‑pressure and high‑temperature working conditions.
- KP30 = pump; matching gear motor is KM30. Identical installation dimensions, flange and shaft options for pump‑motor interchange.
- Multiple mounting choices: SAE and ISO‑European standard flanges; various keyed / splined shafts; side‑port or rear‑port configurations available.
- Multi‑section tandem capability: can be assembled as double‑pump or triple‑pump combinations.
- Optional integrated cartridge valves: relief valve, anti‑cavitation valve, priority valve, load‑sensing priority valve, solenoid bypass valve to reduce external hydraulic components.
- Low‑noise performance, long service life for heavy‑duty mobile machinery.
Typical Applications
