For hydraulic systems that need to power three distinct circuits from a single drive, KCL’s KT Denison-Type Triple Pumps combine three independent vane pumping elements into one compact housing. Engineered to match Denison’s T67 triple-pump specifications, this configuration is the natural next step up from our double pump line for machinery with genuinely complex, multi-function hydraulic requirements.

Why Some Systems Need Three Circuits

Complex industrial machinery — particularly large injection molding machines, multi-axis machine tools, and heavy industrial power units — often requires more than two independent hydraulic functions running simultaneously. A large injection molding machine, for example, might need separate circuits for clamping, injection, and ejection, each with different pressure and flow characteristics. Rather than sourcing three standalone pumps and engineering a complex multi-drive coupling arrangement, a triple pump consolidates all three pumping elements into a single unit driven off one motor shaft.

This consolidation reduces the mechanical complexity of your power unit design, cuts down on the number of separate components that need mounting, alignment, and maintenance, and can meaningfully reduce the physical footprint of your hydraulic power unit compared to running three discrete pumps.

Engineering Consistency Across All Three Elements

Each of the three pumping elements within a KT Triple Pump is built on the same intra-vane mechanism used throughout our KT Series line — the design principle that balances hydraulic loading on the rotor to minimize pressure ripple and internal leakage while keeping noise levels low. Combining three pumping elements into one housing doesn’t mean any individual element sacrifices the performance characteristics that make the KT Series reliable.

Displacement combinations across the three elements can be tailored to match your specific circuit requirements — for example, pairing a higher-displacement element for a high-flow circuit with two lower-displacement elements for auxiliary functions, all within the same integrated unit.

Modular Servicing, Even in a Triple Configuration

The cartridge-based modular design that defines the KT Series carries through to the triple pump configuration. This means that if one of the three pumping elements requires maintenance or a displacement change, your maintenance team can typically service that specific cartridge without a full teardown of the entire unit — an important consideration when a single triple pump is responsible for three separate functions on a production-critical machine.

Configuration and Compatibility

As with our single and double pump lines, KT Denison-Type Triple Pumps are available across multiple shaft configurations, porting arrangements, rotation directions, and seal class options for both standard mineral oil and fire-resistant fluid compatibility. Maximum pressure ratings vary by frame size and displacement combination, generally consistent with the pressure ranges available across the broader KT Series.

Typical Applications

Triple pump configurations are most commonly specified for:

• Large injection molding machines requiring simultaneous clamping, injection, and ejection circuits
• Multi-function machine tools with three or more independent hydraulic-driven operations
• Heavy industrial power units consolidating multiple downstream circuit requirements into a single drive source
• Specialized OEM equipment where minimizing the number of discrete pump units simplifies overall machine design

Why Choose KCL’s KT Denison-Type Triple Pump

Consolidating three hydraulic circuits into one drive unit is a significant design decision, and it’s one that depends entirely on getting the displacement combination, pressure ratings, and configuration details right the first time. KCL’s engineering team works directly with OEM customers to specify triple pump configurations that match the actual demands of each individual circuit — not a generic, one-size-fits-all combination.

Manufactured under the same ISO 9001:2015 certified quality systems as the rest of our product range, and backed by more than four decades of dedicated hydraulic pump manufacturing experience, KCL’s Triple Pump line gives you a verified, interchangeable alternative to Denison’s T67 series without compromising on the engineering precision your multi-circuit application demands.
