2 eneral Information D-TP and TPL pumps are made of Teflon TM PTF and Teflon TM PTF electro conductive housing material respectively. With the updated and optimized design, the pumps distinguish themselves through their simple, robust and rugged construction. Universal flange design (JIS, NSI and DIN combined) enables for flexible global deployment. Key Features Sizes The DP Teflon TM PTF pumps provide for fewer leakage paths through the implementation of integrated valve seats, manifolds with integrated flange connection, block-mounted pump chambers and air chambers and the rib design of DP diaphragms Improved valve ball guidance increases dry suction lift by up to 0%* versus previous designs Maintenance downtime is reduced by up to 0% and the pump weight is up to % lighter compared to our competitors *ccording to internal testing Type (½ ) 2 ( ) 0 (½ ) 0 (2 ) 0 ( ) TP - TPL - Size pplications (½ ) 2 ( ) 0 (½ ) Dry suction height (mwc)* Max. allowable particle size (mm), Weight (kg),2 2,0, 9 * Wet suction height.m for all sizes D-TP/ TPL pumps guarantee a gentle pumping of low and high viscous products and shear-sensitive products. The main applications for TP/ TPL pumps can be found in the chemical industry (especially for aggressive, caustic and acidic fluids). The electro conductive pump (TPL) is suitable for the usage in explosion endangered gas & dust areas. 0 (2 ) 2

6 Performance Curves xample for pump selection Required is 2 m³/h as the flow rate at a discharge pressure of bar. Recommend is the D2 for this application. The needed air supply pressure is, bar. This equals an air consumption rate of m³/h (between QI = 0 m³/h and QI = 20 m³/h).

7 ccessories and utomation ctive Pulsation Dampers Stroke Counter Diaphragm leakage monitoring system ctive pulsation dampers are particularly suitable for intermittent operating conditions and, due to their integrated control, they automatically adjust to provide an optimal degree of damping. separate air supply is required. s with the air-operated double diaphragm pumps, a principle guiding the development of pulsation dampners is the modular use of common components. Pulsation dampers require minimum maintenance and are, subject to the requirements of the application, available in the same housing and diaphragm materials as the pump. The stroke counter sensor counts each cycle of the diaphragm movement. Multiplying the number of cycles with the pump chamber volumes, the discharge flow rate can be determined. For dosing applications, the stroke counter provides for precise measurement and accurate regulation. The stroke counter sensor is located within the center block and provides an electrical output each time the diaphragm is in the end position. The stroke counter consists of a sensor and an electronic amplifier/ regulator. the sensor can be used in TX certified pumps. In case of diaphragm failure occurs, the pumped fluid enters the air chamber and triggers the sensor. The sensor sends subsequently an electrical output to the monitoring device for evaluation of the signal. The control unit switches of the air supply to the air valve, and thus halting the operation of the pump. Two sensors per pump (one per chamber) are installed. Two types of sensors are available: Conductivity Measurement, Stan dard (orange) for conductive products. Capacity System, TX (blue) for non-conductive products and approved for TX-certified pumps.
