ORLITA® DR Rotating Plunger Metering Pump

The ORLITA® DR range has a valveless rotating plunger-type dosing head. It functions by means of a simultaneous oscillating and rotating plunger action. The impeller itself opens and closes the suction and pressure side. This means the pump does not need valves and can be operated in a broad high frequency range.   This working principle allows exact dosing of highly viscous media, which may also have solid constituents.

Advantages

• Dosing of media with a proportion of solid constituents and therefore valveless
• Dosing of highly viscous media up to 106 mPas
• Broad application spectrum: Operating pressure up to 630 bar, temperature range – 40°C to +400°C
• Dosing precision ± 0.5%
• Broad stroke frequency range

Areas of application

Dosing of highly viscous media containing solids, for example in the food industry.

Features

• Performance range 0 -4,000 l/h per pump head, max. pressure 630 bar.
• Work materials: pump head made of stainless steel, cylinder and plungers with wear-resistant surface coating. Depending on the area of application, other high-performance materials are also available.
• The play between the plunger and cylinder responsible for the sealing effect is selected according to viscosity.
• Lanterns at the rear head end, either as a collection annular space for leakage or pressurised with a blocking medium
• The lantern is sealed with elastomer lipped sealing rings
• Conveyance direction can be selected according to the fitted position of the plunger.

Options

• Ceramic plungers and bushing
• Pump head with heating or cooling cover
• Without seal with metallic sealing lantern
• Other options such as electrical stroke adjustment on request
