HYDRA is an electric airless hydraulic piston pump. It has been designed for spraying all kind of thixotropic pruducts in building, water-proofing application, industrial carpentry. It is ideal for plaster-applicators who want to have a new technology for airless plaster applications or stuccoworks on walls. HYDRA allows the maximum efficiency and a long life.
The electric motor is H class, that means: maximum quality and safety. It can work in very bad conditions and with very high temperature. An automatic system stops the pump when exceeding the electric safety limits. All parts in contact with the product are in stainless steel in order to ensure the highest performance.

HYDRA series are new electric airless hydraulic piston pumps, high power, designed for spraying and injecting with no compromise all products used in building, mechanics, woodworkings, and carpentry. These really are very strong and reliable pumps .
A piston pump takes in the coating material by suction and conveys it to the tip. Pressed through the tip at a pressure of up to a maximum of 3300 PSI (228 bar, 22.8 MPa), the coating material is atomised. This high pressure has the effect of micro fine atomization of the coating material. As no air is used in this process, it is described as an AIRLESS process.
This method of spraying has the advantages of finest atomization, cloudless operation and a smooth, bubble-free surface. As well as these, the advantages of the speed of work and convenience must be mentioned.
FUNCTIONING OF THE UNIT
W.I.T. HYDRA Series are high-pressure spraying units driven by either a gasoline engine or electric motor.
The gasoline engine or electric motor drives the hydraulic pump by means of a V-belt which is under the belt cover. Hydraulic oil flows to the hydraulic motor and then moves the piston up and down in the material feed pump.
The inlet valve is opened automatically by the upwards movement of the piston. The outlet valve is opened when the piston moves downward.
The coating material flows under high pressure through the high-pressure hose to the spray gun. When the coating material exits from the tip it atomizes.
The pressure control valve controls the volume and the operating pressure of the coating material.
The main area of application are thick layers of highly viscous coating material for large areas and a high consumption of material.
Priming and final coating of large areas, sealing, impregnation, construction sanitation, façade protection and renovation, rust protection and building protection, roof coating, roof sealing, concrete sanitation, as well as heavy corrosion protection.
The unit is able to process coating materials with up to 50.000 / 65.000 mPas. If highly viscous coating materials cannot be taken in or the performance of the unit is to low, the paint must be diluted in accordance with the manufacturer‘s instructions.
Attention: Make sure, when stirring up with motor-driven agitators that no air bubbles are stirred in. Air bubbles disturb when spraying and can, in fact, lead to interruption of operation.
COATING MATERIALS WITH ABRASIVE MATERIALS
These particles have a strong wear and tear effect on valves and tips, but also on the spray gun. This impairs the durability of these wearing parts considerably.
TWO-COMPONENT COATING MATERIAL
The appropriate processing time must be adhered to exactly.
Within this time rinse through and clean the unit meticulously with the appropriate cleaning agents.
Sufficient filtering is required for fault-free operation. The unit is equipped with a suction filter, an insertion filter in the spray gun and a high pressure filter on the unit. Regular inspection of these filters for damage or soiling is urgently recommended.
