Built for Demanding Ultra-Pure Deionised Water Applications

The Cat Pumps XD-Series plunger pumps are purpose-built for one of the most demanding challenges in industrial fluid handling: ultra-pure deionised (DI) water applications.

Designed specifically to overcome the unique difficulties associated with DI water systems, the XD-Series delivers dependable high-pressure performance, long service life and improved operational efficiency across a wide range of high-purity industries.

Unlike conventional pump technologies that can struggle when exposed to deionised water due to its low lubricity and corrosive characteristics, the XD-Series incorporates advanced engineering features that enable stable and reliable operation in high-purity environments. This makes the range particularly suitable for industries where maintaining fluid purity and system reliability is critical.

Engineered for High-Purity Water Performance

One of the defining advantages of the XD-Series is its specialised seal technology. The pumps utilise a combination of proprietary low-pressure seals and advanced high-pressure packings that allow efficient operation without requiring a freshwater flush system.

In many conventional DI water pumping systems, flush systems are necessary to protect seals and internal components from premature wear. By eliminating this requirement, the XD-Series helps simplify overall system design while reducing water consumption and lowering operational complexity. These benefits are increasingly important for manufacturers seeking improved sustainability performance and reduced operating costs.

The simplified design also supports easier installation and maintenance while reducing the number of auxiliary components required within the system.

Corrosion Resistance for Aggressive DI Water Environments

Deionised water is known for being particularly aggressive towards many materials used in standard pumping systems. To address this challenge, the Cat Pumps XD-Series incorporates 316 stainless steel wetted components along with precision-engineered valve assemblies designed to resist corrosion while preserving fluid purity.

This robust material selection helps maintain long-term reliability in demanding operating environments where contamination control is essential. The pumps are ideally suited to industries such as semiconductor manufacturing, pharmaceutical production, electronics manufacturing and other high-specification industrial processes where ultra-pure water systems play a critical role.

The corrosion-resistant design also contributes to longer operational life and reduced maintenance requirements compared with conventional pumping technologies operating in similar applications.

Built for Continuous-Duty Industrial Operation

Reliability remains central to the XD-Series design philosophy. The pumps feature high-strength connecting rods, ceramic plungers and precision-machined crankcases that support continuous-duty operation under high pressures.

An integrated oil porting system provides consistent lubrication throughout operation, helping to minimise wear on critical components and support extended operating cycles.

This level of mechanical durability is essential in industrial environments where unplanned downtime can have a significant impact on productivity, process stability and operating costs.

The heavy-duty construction also enables the pumps to maintain performance consistency under demanding process conditions, making them suitable for applications requiring continuous high-pressure fluid delivery.

Reduced Maintenance and Lower Operating Costs

Maintenance efficiency is another major advantage of the XD-Series range. The advanced seal system delivers significantly extended service intervals, often lasting several times longer than conventional pump designs.

By removing the need for auxiliary flushing systems, operators can also reduce maintenance complexity, lower consumable usage and minimise downtime associated with servicing additional system components. This contributes to improved overall cost efficiency across the lifetime of the equipment.

For facilities focused on improving operational reliability and reducing total cost of ownership, these maintenance advantages can provide measurable long-term value.

Flexible Performance Across Multiple Applications

With flow rates of up to 170 lpm and operating pressures reaching 152 bar, the Cat Pumps XD-Series offers the flexibility required for a broad range of industrial high-purity water applications.

Its combination of durability, corrosion resistance and high-pressure capability makes the range suitable for applications including:

Semiconductor manufacturing
Pharmaceutical processing
Electronics production
High-purity cleaning systems
Industrial DI water transfer
Precision manufacturing processes
Laboratory and research facilities

As demand continues to grow for reliable high-purity water systems across advanced manufacturing sectors, the XD-Series provides a proven solution capable of delivering long-term reliability, operational efficiency and reduced maintenance demands.

A Reliable Solution for Deionised Water Pumping Systems

The Cat Pumps XD-Series brings together advanced seal technology, corrosion-resistant materials and robust mechanical construction to meet the challenges of ultra-pure deionised water operation.

By combining simplified system design with continuous-duty performance and extended service intervals, the XD-Series delivers a dependable and cost-effective solution for industries where fluid purity, reliability and operational efficiency are essential.
