620R continuous tubing pumphead

620R pumphead accommodates 3.2mm wall continuous tubing in four bore sizes from 6.4mm to 15.9mm, giving up to  4.2 gpm flow at up to 30 psi pressure.
Tubing is available in eight materials for almost any chemical requirement.
620RE LoadSure tube element pumphead

620RE is a high-performance, accurate, two-roller pumphead with LoadSure rapid tube element change technology.
4mm wall elements in 12mm or 17mm bore sizes allow pressures up to 60psi and flow rates up to 4.8 gpm.
Elements are available with industry-standard tri-clamp sanitary fittings; and with Cam and Groove fittings for industry.
620RE4 LoadSure tube element pumphead

620RE4 is a high-performance, accurate, four-roller pumphead with LoadSure rapid tube element change technology. 4mm wall elements in 12mm or 17mm bore sizes allow pressures up to 60 psi and flow rates up to 3.32 gpm with minimized pulsation.
Elements are available with industry-standard tri-clamp sanitary fittings; and with Cam and Groove fittings for industry.
620L twin-channel pumphead

620L is a specialist 2 bar, six-roller pumphead designed for accurate dispensing to ±0.5%. Minimal pulsation is achieved by splitting the inlet flow into two tubes passing over twin, offset tracks. The two sets of out-of-phase pulses cancel each other out when the channels merge.
Uses 4.0mm wall Y-elements in a choice of six materials, or continuous tubing
Two single channels are also available
Tubing choices: 8mm, 12mm, and 16mm bore, offering flow rates from 0.00053 to 3.3 gpm
Dispenses 500ml in 3.5 seconds


Simple-to use HMI requiring minimal key presses to reduce chances of costly errors. Flow proportional to pump speed over 2,650:1 control range. NEMA 2 and NEMA 4X cased pumps for washdown environments.
630S - NEMA 2 and 630SN - NEMA 4X are simple, plug-in and switch on pumps offering economy of ownership. Ultimate process security with a 3 level PIN lock.
630U - NEMA 2 and 630UN - NEMA 4X with all the features of the S/SN models, plus configurable inputs and outputs.
630Du - NEMA 2 and 630DuN - NEMA 4X with configurable inputs and outputs, plus RS232 and NEMA 2 RS484.
630Bp -  NEMA 2 and 630BpN - NEMA 4X Real time communication makes your process secure and flexible. Bus speed 9.6 kbits/s up to 12000 kbits/s connectivity
