Diaphragm pumps

DDA dosing pumps Application DDA pumps have integrated digital control and is used for dosing of CIP concentrate. For other chemicals check the compatibility. Benefits Display showing how much you are dosing Many control possibilities as standard (0-4mA, Batch, Timer, External start stop) Turn down ratio up to 1:3000 depending on model Flow capacity: Up to 200 l/h Pressure: Up to 16 bar Pump head material: Stainless steel

The SMART Digital DDA is a compact positive displacement, diaphragm dosing pump with variable-speed drive (stepper motor) and intelligent control electronics with minimum energy consumption. The SMART Digital Dosing series operates at full stroke length to ensure optimum accuracy, priming and suction, even for high-viscosity or degassing liquids. The duration of each discharge stroke varies according to the capacity set, resulting in optimum smooth and continuous discharge flow. The click-stop mounting plate allows installation in three different positions without using any additional accessories. The control cube can be turned easily into front, left or right position. The click wheel and the multi-colored backlit graphical, plain-text LC display make commissioning and operation intuitive. Operation modes Timer-based batch function (Dosing timer, cycle or week). Manual dosing in ml/h, I/h or GPH. Pulse control in ml/pulse (incl. memory function). Analog control 0/4-20 mA (scalable). Pulse-based batch function in ml, l or gal. Features Save and load customized settings as well as reload of factory settings. Auto deaeration during pump standby to avoid breakdowns due to air-locking. Two Slow Mode steps (anti-cavitation), 50 % (maximum flow: 15 l/h) and 25 % (maximum flow: 7.5 l/h), e.g. for high-viscosity or degassing liquids. Service information display to show when service and which wear-part order number is required. Two-step key lock function to protect the pump against unauthorized access. Additional display function to provide further information, e.g. the actual mA input signal. Counter for total dosed volume (resettable), operating hours, etc. Signal input/outputs Input for pulse, analog 0/4-20mA, external stop. Input for low-level and empty-tank signal. Two potential-free output relays for max. 30 V AC/DC (configurable, e.g. alarm, stroke signal, pump dosing, timer etc.) Output analog 0/4-20mA. Fieldbus communication interface (GeniBus ,also for additional Profibus DP E-box to retrofit). Electrical data Maximum power input – P1: 24 W Mains frequency: 50/60 Hz Rated voltage: 1 x 100-240 V Enclosure class (IEC 34-5): IP65 / NEMA 4X

DME dosing pumps Application DME pumps have integrated digital control and is used for dosing of CIP concentrate. For other chemicals check the compatibility. Benefits Display showing how much you are dosing Many control possibilities as standard (0-4mA, Batch, Timer, External start stop) Turn down ratio up to 1:3000 depending on model Flow capacity: Up to 940 l/h Pressure: Up to 16 bar Pump head material: Stainless steel

Compact positive displacement diaphragm dosing pump, with integrated variable speed motor drive, in an IP 65 plastic enclosure. The pump is designed for optimum user-friendliness, accuracy and reliability and is equipped with a logical control panel with one-touch buttons and a multi-language backlight display. The capacity to be dosed in each function is set directly in l, ml or US-gal per hour. For enhanced accuracy, the pump can be calibrated to the actual installation by means of a simple calibration function. The turndown ratio is 1 to 800 with the same accuracy and uniform dosage with reduced pulsation throughout the capacity range. The pump is also equipped with a maximum capacity function (100%) that allows the pump to work for a preset time at maximum capacity for priming or ordinary maintenance without changing pump settings. Operating modes Manual dosing with direct setting in ml/hour, l/hour or US-gal/hour External pulse control from external controller or water meter with direct setting in ml/pulse External analog 4-20, 20-4, 0-20 and 20-0 mA control with possibility to adjust the pump capacity at maximum signal. Timer-based batch function (internal timer). Pulse-based batch function (external pulse). Features On-site calibration function for calibrating the pump to the actual installation. Anti-cavitation function for high-viscosity, gassing liquids or long suction lines. Maximum capacity limitation. Counters for numbers of pump strokes, operation hours and power on/off. 14 optional display languages. Level control with input for two level signals. Alarm relay output. Technical Approvals on nameplate: CE,EAC Electrical data Power input – P1: 240 W Mains frequency: 50/60 Hz Rated voltage: 1 x 100-240 V Rated current: 2.4-1 A

DMX dosing pumps Application DMX pumps have integrated mechanical control and is used for dosing of CIP concentrate. For other chemicals check the compatibility. Benefits Low cost basic dosing pump Up to 525 l/h Pump head in stainless steel Up to 10 bar

The DMX series pump is a versatile positive displacement diaphragm dosing pump. The diaphragm is coupled mechanically via a precise gear-excentre-tapet-system to a high efficiency AC motor. The dosing capacity is adjusted by varying the stroke length at the stroke adjustment knob in the ratio 1:10. Features Robust industrial pump with aluminum enclosure Easy to install and operate design Long life PTFE coated diaphragm Optimum capacity and stroke frequency graduation Dosing flow variation < ±1.5%, linearity >±4% Materials Dosing head: Stainless steel, 1.4571 Valve ball: 316 L Gasket: PTFE Electrical data Mains frequency: 50 Hz Rated voltage: 3 x 230/400 V Enclosure class (IEC 34-5): IP 65/F

TR9/TR20/T50/T100 transport pumps Application There are air-operated diaphragm pumps made from polyethylene (PE) and are suitable for pumping of almost any kind of liquid whether it is viscous, corrosive and chemically aggressive or with solids. Benefits Run dry without damage. Self priming up to 5 m from dry suction pipe. Air valve made from AISI 316L stainless steel. Temperature: Max 70ºC . Few components means low downtime and maintenance costs.
