High resistance to pressure transients and aggressive synthetic coolants

Walrus TPH Horizontal Multistage Centrifugal Pumps

Walrus TPH horizontal multistage centrifugal pumps are designed for fluid circulation, parts washers, and industrial pressure boosting. The stainless steel SUS304/SUS316 construction provides dependable corrosion resistance when handling purified water and mildly aggressive industrial liquids.

Pump casing, impellers, and shaft fabricated from SUS304 or SUS316 stainless
Operating liquid temperature capability from 0°C up to +90°C continuously
Compact close-coupled horizontal footprint with quiet hydraulic performance
Widely applied in reverse osmosis, industrial washing, and boiler feed water

Walrus TPR & TPRK Vertical Multistage In-Line Pumps

Walrus TPR and TPRK series are heavy-duty vertical multistage pumps delivering heads up to 320 meters with IE3/IE4 premium efficiency motors. TPRK models incorporate a patented drain-back leakage return system, preventing external spray during heavy-duty machine tool cooling cycles.

Discharge head capability up to 320 meters with fluid flow up to 2000 L/min
Premium energy-saving IE3 and IE4 electric motors rated up to 45 kW
Patented drain-back chamber returns minor seal bypass safely to tank
In-line suction and discharge ports simplify plant piping installation

Walrus Liquid Cooling & Custom Walrus Fit Integration

Walrus engineers intelligent pump systems for AI data center liquid cooling and high-density computing clusters. The Walrus Fit program customizes hydraulic units across operating pressures from 1 to 70 bar, fluid characteristics, current limits, and building management interfaces.

Operating pressure envelopes from 1 to 70 bar for advanced data center cooling
Intelligent microprocessor inverter controls for dynamic thermal management
One-stop Walrus Fit engineering customized for server rack heat dissipation
Continuous telemetry feedback covering flow velocity, pressure, and thermal delta

Selection of Walrus TPAK Immersible Machine Tool Coolant Pumps

Walrus TPAK immersible centrifugal coolant pumps are selected based on cutting fluid flow requirements and tank installation depth.

The model portfolio offers stem lengths ranging from 150 to 350 mm, allowing straightforward drop-in integration into compact coolant sumps across CNC lathes and milling machines.

The sealless co-axial configuration prevents seal failures when circulating water-soluble emulsions and neat mineral oils containing fine swarf particles. During replacement, technicians verify mounting flange bolt circle dimensions, discharge port threads, and correct motor phase rotation.

High-Pressure Through-Spindle Cooling with TPCK & TPHK Pumps

Walrus TPCK and TPHK pump series deliver high-pressure fluid delivery up to 25 bar for through-spindle cooling in deep-hole drilling and high-feed milling. The cartridge-type mechanical shaft seal allows swift on-site maintenance without disassembling the primary hydraulic stack.

High-pressure coolant lines require an in-line pressure relief bypass valve and secondary filtration down to 25 microns. This protective arrangement shields the stainless steel SUS304/SUS316 impellers and diffusers from cavitation damage and high-velocity abrasive erosion.

Multistage Horizontal TPH Pumps in Industrial Cleaning Systems

Walrus TPH horizontal multistage centrifugal pumps circulate industrial washing solutions and demineralized rinse water in parts cleaning tunnels. All fluid contact components are cast in corrosion-resistant stainless steel, sustaining continuous operation at temperatures up to +90°C.

To safeguard the assembly against dry run conditions, automated flow switches or pressure sensors are wired into the main control circuit. Controlled soft starts protect internal mechanical seals and pipe fittings from hydrodynamic shock when spray nozzles open cyclically.

Vertical In-Line TPR Pumps in Industrial Water Treatment Plants

Walrus TPR vertical multistage pumps generate discharge pressures up to 320 meters head for reverse osmosis membranes, ultrafiltration, and boiler feed water systems. In-line suction and discharge ports simplify structural piping without requiring complex manifold offsets.

Premium IE3 and IE4 efficiency electric motors reduce energy costs during round-the-clock industrial duty. TPRK models incorporate a patented drain-back leakage return chamber, preventing external coolant misting as mechanical seal faces wear over extended operating intervals.

Data Center Liquid Cooling and Customized Walrus Fit Integration

In direct-to-chip and immersion liquid cooling architectures for AI data centers, Walrus pump skids deliver reliable heat extraction across pressures from 1 to 70 bar. The Walrus Fit engineering framework configures hydraulic geometry and seals to match dielectric and glycol-water fluids.

Intelligent inverter controls interface with building management systems, continuously matching pump rotational speed to dynamic server thermal loads while maintaining constant differential pressure across cooling cold plates.
