The axial piston fixed pump AHP PF - 20 is designed for various applications in open hydraulic circuits. At the figure No. 2 is drawn cross sectional view of the piston pump.
The shaft is supported by two tapered roller bearing. Design of the end of input shaft you can find on the page 16 of this catalogue. Hydraulic pump is closed by the front and rear cover. The rear cover also serves for connection of the high-pressure and suction ports. The angle of the swash plate is fixed on 18°.
Fig. 2: Cross sectional view of fixed pump.
Flange with centering diameter according to the standard SAE is bolted to the front cover. Tightness of the case around the exiting part of the shaft is protected by the shaft seal for max. pressure 0,25 MPa (intermittent 0,5 MPa).

With its new PRO high-pressure range, KMT Waterjet Systems sets new standards in the field of waterjet cutting. PRO stands for waterjet cutting technology with operating pressures of up to 6200 bar. The new range of products includes of course all necessary components and accessories - from high-pressure generation units to orifices that guide the cutting jet with great precision onto the material. The maximum pressure of 6200 bar represents an increase of nearly 50% over pressures used in conventional equipment!
The advantages offered by this leap in technology are obvious:
- Higher cutting speeds
- Improved cutting edge quality
- Lower abrasive consumption

PVK units are axial piston pumps of slipper design. Rotor of this pump is driven by shaft which is supported by 2 roller bearings. Inside of the rotor, there are moving 9, hydrostatically balanced, pistons parallel with an axis of rotation. They are slipping on the inclined thrust plate which is placed inside of the swash plate and this way, the pistons are moving with a straight-line motion.
They create 1 suction and 1 pressure stroke per revolution. Fluid direction is performed by frontal rotational distribution. Single cylinders are joined either with a suction channel or a pressure one of the end cap during a motion of the distributor. Swash plate angle is possible to regulate continuously with various ways of control and automatic regulations (mentioned in 5, 5.1 and 9.1) which are part of axial piston pump.
These units are designed for conversion of mechanical energy into pressure one. They can be used in closed loops of various machines (e.g. road, construction, grading, agricultural, forest, mining etc.) where is demanded a continuous change of input parameters. The loop has to be designed such way that pump parameters, which are determined by technical conditions and project of the specific application , must not be exceeded during an operation.

Variable displacement axial piston pumps of swash plate design series AHP-10 are designed for various applications working in closed hydrostatic circuit.
Fluid flow is in proportional relation with speed and displacement of pump, which can be increased with changes of swash plate angle from zero to maximum. Standard pump is equipped with internal charge pump - G-rotor type, manifold assembly with block of flushing and two pressure relief valves on the high pressure ports.
Relief valves protect the hydrostatic transmission from overloads. Standard pump is equipped with mechanical - hydraulic servo valve with mechanical feedback. Tightness of the case around the exiting part of the shaft is protected by the shaft seal for max. pressure 0,25 MPa (intermittent 0,5 MPa).

The InLine variable displacement pump type V30D and V30E work according to the swash plate principle and are intended for open circuit operation in industrial and mobile hydraulics. There is also an option for a thru-shaft for flange mounting additional variable and fixed displacement pumps. Type V30E is intended as successor of V30D, where the completely new development allowed to realize state of the art pump design. This concerns primarily the optimization of self-suction speed rating, minimized noise level, weight, and pulsation as well as increased service life.
These pumps are suited for a wide range of applications due to their low running noise and various pump controllers.
Hydraulic circuits where several outlet flows are required can be fed either by one individual pump or a multiple pump. Main benefit of these pumps are the sturdy design, the good performance/weight ratio, long service life
due to oversized bearings, and the swash plate angle indicator.

The SP700 and VP700 are new battery powered backpack units weighing no more than 18KG providing hydraulic power for cutting tools, and other hydraulic equipment such as Jaws of Life® and hydraulic jacks as used by emergency services and in many other situations.
Jon Lye, Managing Director of GSF explains: “The uniqueness of the Interfron range definitely improves emergency operations; it’s an innovation in design and one we believe will make a dramatic difference to the industry.”
Indeed the range of battery powered backpacks are unique in the respect that it gives emergency crews complete freedom from petrol driven or vehicle mounted power supplies; no hydraulic extensions and no attachments mean no entanglements, which, in low visibility high risk environments, reduce accidents and increase access to enclosed and otherwise inaccessible spaces.
At the heart of the range is the SP700 and the VP700, both of which can be fitted with the appropriate hydraulic connectors, enabling the units to operate rescue tools from all major manufacturers, including: Holmatro, Amkus, Lukas, Zumro, Weber, TNT, Lancier, Nike Centaur, ResOtec and Enerpac. The units can be adjusted to use hydraulic pressure at 5100, 9200 and 10500 psi. Each unit has a total weight (approx) 18kg (40lbs).
This Interfron range represents a very exciting addition to GSF’s long established market leadership on high strength shock resistant telescopic slides, and our state of the art Promounts range of mounting gear, used to secure every type of gear and equipment onto emergency and defence vehicles.

Hydratron Air Operated Hydraulic Pumps are capable of generating output pressures of up to 45,800 PSI ( 3,160 Bar ) when supplied with just 100 PSI ( 7 Bar ) air pressure. There are 4 model ranges offering flows of up to 7 gpm ( 31.7 Ltr per min ).
These pumps will maintain pressure within a system indefinitely without consuming power or generating heat plus their output pressure can be infinitely varied by simply regulating the driving air pressure.
These pumps are ideal for pressure testing, chemical injection and for hydraulic power applications. Standard models are suitable for oil or water service having wetted parts manufactured from stainless steel and aluminium bronze. Options include all stainless steel wetted parts for pumping more aggressive chemicals with isolation chambers which keep the pneumatic and hydraulic sections of the pumps completely separate. This is particularly desirable when pumping hazardous fluids.
Pumps can be supplied individually or mounted in Power Pack form in which case they are mounted within metal frames complete with reservoirs, all necessary air controls, output pressure gauges and pressure release valves.

M Series pumps are open circuit, axial piston designs. A variety of controls provides the ability to match the pumps to each application.
A strong, proven rotating group allows the pumps to handle pressures to 280 bar (4000 psi) continuous and 320 bar (4600 psi) intermittent - with less maintenance cost. Each frame can also contain a 230 bar (3300 psi) higher flow rotating group that provides additional application flexibility. High-load bearings and a stiff drive shaft help provide a pump life of 30,000 hours (@ 65% rated pressure), reducing operating costs and extending machine life.
M Series pumps feature a saddle-type yoke with steel-backed polymer bearings. The stiff yoke reduces deflection and allows even loading of bearings, improving life. A single control piston reduces loading on the yoke, resulting in reduced pump size that allows installation in tighter locations.
M Series pumps operate at a level of quietness that exceeds the requirements of today's demanding industrial conditions. The pumps feature a unique three-piece envelope (flange, housing and valve block) specifically created for low fluid-borne and structureborne noise levels. Another pump feature - a bimetal timing plate - improves pump filling characteristics that, in turn, reduces fluid-borne noise and extends pump life.
