“Hydronic Publish HP3 Literature”
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.
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.”
New Product Press Release

‘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.
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
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.
‘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.
