Watson-Marlow 630 Series Process Pumps with 620L low pulsation pumphead

630Du and DuN, 630Bp and BpN peristaltic process pumps fitted with 620L high accuracy, low pulse pumphead or 620LG pumphead for GORE® STA-PURE Series PCS® or GORE® STA-PURE Series PFL® tube630 range of peristaltic process pumps offer four drive options, color display and intuitive menu structures provide visual status indication and minimal key pressesFlow rates up to 3.25 gpmIndustrial integration - manual, remote, Analog and digital communication, plus PROFIBUSKeypad incorporates 3-level security PIN lockThe 620L pumphead splits fluid flow into twin offset channels, and reunites them so that pulsation is eliminated to allow accurate dosingDu and Bp pumps are NEMA 2 rated cased pumps. DuN and BpN are NEMA 4X rated cased pumps620L twin-channel pumphead620L 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 tubingTwo single channels are also availableTubing choices: 8mm, 12mm, and 16mm bore, offering flow rates from  0.00053 to 3.3 gpmDispenses 500ml in 3.5 seconds620RE4 LoadSure tube element pumphead620RE4 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.620RE LoadSure tube element pumphead620RE 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 60 psi 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.620R continuous tubing pumphead620R 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.
