New Literature Press Release

To be reproduced in the general media, Spring, 2003

Publish date - March 24, 2003

“Hydronic Publish HP3 Literature”

“All six ranges of the Hydronic product line have new literature.  Each model in every range is listed with new easy-to-read performance graphs and step-by-step model codes.

The P901 range of miniature manifold pumps has seven models.  Their square shape and compact efficiency has been dubbed “cubic power”  and this has given rise to the new  logo echoing the   company name.


While most Hydronic power units can achieve 10,000 psi, some will go well beyond up to 26,500 psi.  Pumping synthetic oils and brake fluid is standard for most models and stainless steel version are available.

The company already has the P820 range of hydraulic power units with D03 interfaces as well as its sister range, the P826, taking the two horsepower level up to 10,000 psi and beyond.  These power units are described in detail on the new literature and further information is available from the website, hydroniccorp.com.”

“Cubic Power Launched”

“The ‘power in a box’ concept leaps from miniature to real horsepower size with the unveiling of the P923 series by Hydronic Corporation. This puts 1-½ gallons per minute and 3,000 psi directly onto your D03 manifold with its two-bolt interface.

Rather than being restricted to the more traditional pressure generating tools, reciprocating pumps driven by compressed air have become the standard base for Hydronic power units. The innovation of manifold mounting the pumps, in place of screwed line connections, appeared at the IFPE 2002 show with the miniature P901 series. The new range brings almost two horsepower in each of seven models covering flows up to 9 gpm and pressures up to 10,000 psi.

The sheer versatility of integrating pumps, valves and other modules together on the same manifold has many advantages. The size of the finished power unit is smaller, requiring less floor space in the customer’s plant. The cost of the unit is less, in both components and labor. There are less leakage points and the unit has a more modern appearance.

Circuits calling for higher horsepower are simply accommodated by extending the manifold and using two pumps, one for flow and one for pressure. A fast approach and high force system, as used in press tools or welding fixtures, would have the 9 gpm and the 5,000 psi pumps mounted side by side on the D03 manifold. They would operate together, combining their flows until the load increased significantly. At this point, the high flow unit would stop automatically and the high-pressure unit to carry on up to its high-pressure setting.

This ‘power on demand’ feature is a considerable benefit in clamping and workholding circuits where high pressure is maintained for a large portion of the work cycle. The mechanism of the pump will continue to move, slowly or quickly, depending on the open path available to the oil. When the workpiece is held firmly, the pump stops and just maintains pressure. This means there is no energy being used, there is no noise, no heat build up, no wear and tear on parts and no degradation of the oil. Large heat sink reservoirs are not necessary and the cost is therefore lower. When the signal is given to release the part being clamped, the pump is allowed to function and actuate the cylinders.
