D.C. Electro-pumps, series ET...
The essential components of series ET elektro pumps are an external gear pump and an elctro motor.
The 12 and 24 VDC motors feature high efficiencies and precision-balanced rotors for low-vibration running. They are combined with our AP05 - AP100 external gear-pumps to produce the ET series of electro-pumps, a family of products that are notable for their low noise levels in operation.
Simplicity of construction and reduction in size are the fundamental objectives in the design of the ET electro-pumps.
Advantages
Noise levels have been drastically reduced
Wide range of displacements and electric motor

Capacity to control minimum displacement
The DELTA pumps are designed to regulate flow from maximum flow to flow cancellation mode. However, some applications require a minimum outlet flow to be maintained, regardless of how flow is controlled from maximum to minimum.
Capacity to have a high speed rotation
The rotating speed of the DELTA pumps depends on:
• flow supplied by the pump,
• the fluid viscosity,
• the pressure at inlet point of the pump.
For applications at higher speeds than those indicated, please contact our Technical Department with details of these parameters, to enable us to advise what can be recommended.
■ Features of DELTA pumps
The DELTA pumps are equipped with a maximum displacement control.

The variable volume, pressure compensated design features of this pump combined with significant advancements in noise reduction make this pump a perfect match for many industrial applications.
The controls available provide for standard pressure compensation, load sensing, remote pressure control, and horsepower limiting. These control options permit the machine designer to utilize efficient pump controls that are tailored for the requirements of a hydraulic system. PVX controls are available in both single stage and two stage designs. All of the PVX controls exhibit very good response and recovery times and can incorporate a shock clipper that reduces shock pressure by up to 50%. This feature increases system component life and system stability.
The hydrodynamic journal bearing design is a feature that enhances the quiet operation of this pump, and eliminates the B-10 rating of the unit. A one piece rotor shaft contributes to this rugged design with minimized deflection when under high system loads. The rotor design allows the designer to easily configure a tandem mount rear drive option that provides the flexibility of driving multiple pumps with a common input shaft. This eliminates the need for additional prime movers, when multiple pumps are required.
Porting plates that provide proper timing for the inlet and discharge cycles of the pump, are designed for efficient and quiet operation. These pressure loaded port plates provide optimum running clearance to the rotor and contribute to high volumetric and overall efficiency.

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.
