Emission-free URACA plunger pumps

An important step in environmental protection: The development of an emission-free pump design allows the plunger pump manufacturer URACA to handle critical media under high pressure without them being released into the environment.

Pumping aggressive problem fluids with high displacement and under high pressure is the speciality of URACA plunger pumps.

High pressure plunger pumps from URACA are designed and manufactured for a vast variety of applications with respect to power and pumped medium. The machines normally work in continuous operation. The flow volumes may reach up to 11,000 l/min/2,900 USGPM, the operating pressure is up to 3,000 bar/43,500 psi. Dampers on suction and pressure side enable low pulsation and thus reliable and secure operation of the overall system. A particular advantage are the high rates of efficiency and the related economical operation of the pumps.

Pumping neutral and aggressive thin liquid and viscous as well as abrasive media is no problem for URACA pumps, whereby the temperature ranges may vary from extremely cold up to very high temperatures.

Taking care of the constantly increasing requirements regarding environmental protection, the high pressure pump manufacturer URACA developed a concept that allows the pumping of critical media with plunger pumps under high pressure without the pumped media escaping to the environment.

The aim was to transfer the legal requirements from the BImSchG to a high-pressure plunger pump and prevent its emissions of air pollutants. As a result the safety and health of the operators can be guaranteed. The "TA Luft" (Technical Instructions on Air Quality Control) and its limit values for emissions are used as a basis. Compliance with TA Luft ensures that the valid EU regulations are implemented. In this context, emissions are defined by TA Luft as "the air pollutants emitted by a plant".

The emission-free pump design was realized by using a sophisticated and tailormade sealing concept with special oil sealing at the stuffing box. This prevents the pumped liquid escaping from the plunger pump in the rear stuffing box area.

In general all pump models from small to big can be equiped with this very special sealing method in order to achieve ‘technically tight status in the sense of TA Luft and VDI 2440’.
