Space is often the most valuable resource in industrial environments. Whether you are retrofitting existing plants, designing compact container solutions, or working on offshore platforms – you often need to pack maximum hydraulic power into a minimal area. A vertical pump offers the ideal solution: By shifting from a horizontal to a vertical plane, the required floor space is massively reduced.
Why Choose a Vertical Pump?
While centrifugal pumps in low-pressure ranges are often arranged vertically by design, they reach their physical limits in high-pressure applications. KAMAT plunger pumps are oscillating positive displacement pumps that handle process pressures up to 4,000 bar with an efficiency of over 90 %. The vertical arrangement utilizes the available room height and significantly minimizes the footprint.
This configuration allows for the installation of industrial-grade high-pressure hydraulic power on a very small base area. These systems are used wherever horizontal high-pressure units cannot be positioned due to existing dimensions.
Engineering Requirements for Vertical Installation
The vertical orientation of a high-pressure unit fundamentally changes the physical conditions for the drive unit. In standard configurations, plunger pumps are optimized for horizontal placement. Reliable vertical operation therefore requires specific design adjustments to the internal mechanics:
- Ensuring oil supply: In a horizontal position, oil reaches all bearing points via splash lubrication. In a vertical setup, the lubricant sinks to the lowest point due to gravity. Without active distribution, upper components and crosshead guides would run dry.
- Compensation of component weights: Vertical mounting means the weight of the oscillating parts acts additionally on the guides. A stable lubricant film is mandatory here to neutralize increased friction and wear.
- Crankcase integrity: System-related leakages at the plunger seals must be drained specifically during vertical mounting. Without a design separation between the pump head and the gearbox, medium could travel along the plunger into the oil sump and degrade the lubrication properties.
KAMAT achieves stable continuous operation under these conditions through precise control of the internal oil hydraulics.
Forced Lubrication Instead of Splash Lubrication
Simply rotating a horizontal unit by 90 degrees would lead to lubrication failure. KAMAT addresses this physical risk through a consistent technical modification:
- Active forced lubrication: A gear pump driven directly via the pinion shaft ensures the lubricating oil circuit. This guarantees a continuous supply to all bearing points and crossheads – regardless of the mounting position or speed.
- Prevention of contamination: An optimized sealing concept and modified leakage management ensure that process media do not enter the drive unit. Consequently, maintenance intervals remain identical to the horizontal standard version.
Advantages of a Vertical Pump Configuration
Choosing a vertical pump configuration is usually a structural necessity to increase the power density of a plant. Beyond pure space savings, there are specific benefits for plant design and maintenance.
- Maximum space efficiency: By placing the motor above the pump, the unit’s footprint is reduced to an absolute minimum. This enables high power densities in containers or on ships that would be impossible with horizontal setups.
- Flexibility for retrofits: When modernizing existing plants, the available space is often dictated by the surrounding infrastructure. Vertical pumps allow for a power upgrade up to 4,000 bar without expensive adjustments to the floor space.
- Ergonomics and accessibility: The vertical design often places the valves and seals of the pump head at an ergonomically favorable working height. Since you don’t have to reach over long drive trains, maintenance times in cramped spaces are noticeably shorter.
- Dry installation: Unlike vertical submersible pumps, the KAMAT system operates dry. This allows for permanent visual inspection for leaks and protects the drive unit from external environmental influences.
- Safe maintenance without tank removal: Since the pump does not have to be lifted out of a tank, servicing remains cleaner, and the risk of media contamination during maintenance is minimized.
Applications: Where Vertical Pump Systems Are in Demand
The combination of extreme pressures and limited space is the rule rather than the exception in many industries. Vertical pump systems from KAMAT are used wherever a horizontal installation reaches physical limits or would occupy an uneconomical amount of space:
Performance Classes and Modular Flexibility up to 4,000 bar
At KAMAT, a compact design never means sacrificing performance. Since the drive unit and pump head of the vertical pump are identical to the horizontal version, all mechanical and hydraulic parameters remain fully intact.
Performance data in vertical operation:
- Extreme high pressure: Reliable operation up to 4,000 bar for the most demanding applications.
- High drive power: Support for power up to 1,200 kW, realized through the proven drive unit design.
- Modular design: By using standardized components and various conversion kits, flow rate and pressure can be precisely tailored to the application.
- Identical service life: Thanks to active forced lubrication, vertical units achieve the same service life as horizontal variants.
Users benefit from the full hydraulic power of the K-Series with minimal space requirements. The vertical pump is not a special workaround at KAMAT – it is a fully-fledged, configurable variant of our modular system.

Frequently Asked Questions About Vertical Installation
No. The forced lubrication system ensures reliable oil supply to all bearings and crossheads regardless of gravity. Service life and maintenance intervals are identical to those of horizontal installations.
In most cases, no. Thanks to KAMAT’s modular system, many standard K-Series pumps can be configured for vertical operation, combining proven series technology with installation-specific adaptation.
No, provided they are properly engineered. With the heavier pump unit positioned at the bottom and the motor mounted above, the center of gravity remains low. Frame designs are optimized using FEM analysis to prevent resonance.
Maintenance is considered in the design. Oil naturally collects at the lowest point of the housing, where dedicated drain or extraction points are installed, allowing clean and efficient oil changes.
Vertical configurations are primarily implemented with electric motors, which can be flanged directly to the pump via a compact lantern and flexible coupling. Internal combustion engines are less common due to their limited suitability for vertical operation.
