Product catalog summary
Function of the External Gear Dosing Pump DARTec®
The DARTec® gear dosing pump is composed of several key components including a front plate, center plate, wear plates, rear plate, gear pairs, pump shaft, and drive shaft, all supported by high-precision bearings. The pump features customizable inlet and outlet ports located on the rear plate. It is designed to handle shear and friction-sensitive media efficiently, with adjustable clearances based on medium, differential pressure, and viscosity. The pump can be made lightweight for integration with handling equipment and robots.
Design and Versions
The pump's design includes various components such as a center plate, front plate, driven shaft, seals, drive shaft, sleeve bearings, gears, and rear plates. Shaft seals are chosen based on fluid and temperature resistance, inlet pressure, and other factors. Special versions with different material combinations and coatings are available for enhanced wear resistance.
Accessories and Assembling Options
Available accessories include motors, mechanical couplings, bell housings, base plates, flow meters, and connection plates. Mounting options include pumps with bare shafts or foot brackets, with or without connection plates.
Installation Options Including Motor
Complete units with motors are available, offering installation options such as pumps with bell housing, coupling, and connection plates, or foot brackets for horizontal mounting.
Applications and Fluids
The DARTec® pump is utilized in dosing systems for elastomers, resins, polyurethanes, silicones, and glues, as well as in process engineering for precise dosing of additives, isocyanates, and shear-sensitive media. It provides low-pulsation and precise dosing, rapid pressure build-up, and high efficiency.
Operating Conditions
The pump operates with displacements from 0.1 to 6.0 cc/rev, speeds from 1 to 400 min-1, and viscosities from 1 to 1,000,000 mPa·s. It can handle ambient temperatures from -30°C to +60°C and fluid temperatures from -20°C to +150°C.
Operating Pressures and Speed Ranges
The pump can operate at a maximum pressure of 150 bar with a speed range of 1 to 400 min-1, depending on the viscosity and lubricity of the fluid.
Calculation Basis
Guidelines are provided for dimensioning the required drive capacity and minimum torque, including formulas for calculating power consumption, flow rates, and efficiency.
Specifications and Efficiency
The document outlines efficiency metrics for pumps, including overall efficiency, volumetric efficiency, and mechanical efficiency. A formula is provided for calculating the required driving torque using a conversion constant of 9550.
Viscosity Factors
Viscosity factors are provided for different viscosities ranging from 100 mPa·s to 100,000 mPa·s, affecting discharge pressure and efficiency.
Recommendations for Dimensioning
Higher viscosities require safety margins in motor power calculations. It is advised to select the next higher motor power and coupling torque values based on manufacturer ranges.
Calculation Example
An example calculation is provided for a DARTec® pump, detailing the process of determining theoretical flow rate, performance, and required torque on the pump shaft.
Material Combinations and Versions
The document lists different versions of DARTec® pumps, specifying materials like stainless steel and PTFE for various components, and provides explanations for terms like FKM (fluorrubber) and PTFE (polytetrafluorethylene).
Technical Indications
Speed recommendations are given for different viscosities, both with and without fillers. Conversion factors for various units are also provided.
Temperature Considerations
Pumps are designed for ambient temperatures between -30°C and +60°C. Deviations require consultation with the manufacturer. Fluid temperature affects the selection of housing and sealing materials.
Performance Data and Characteristic Curves
Performance data for different pump sizes and configurations are provided, including nominal volume, tolerance class, and testing viscosity.
Dimensions and Connections
Detailed dimensions and connection sizes for DARTec® pumps are provided, including block size and port connections.
Certifications
The document mentions certifications such as ISO 9001, ISO 14001, and ISO 45001.
