0

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® tube.

  • 630 range of peristaltic process pumps offer four drive options, colour display and intuitive menu structures provide visual status indication and minimal key presses
  • Flow rates up to 12.4 l/min
  • Industrial integration - manual, remote, Analog and digital communication, plus PROFIBUS
  • Keypad incorporates 3-level security PIN lock
  • The 620L pumphead splits fluid flow into twin offset channels, and reunites them so that pulsation is eliminated to allow accurate dosing
  • Du and Bp pumps are IP31 rated cased pumps. DuN and BpN are IP66 rated cased pumps

620L twin-channel pumphead

  • 620L is a specialist 2bar, 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  0.002 to 12.4 litre/min
  • Dispenses 500ml in 3.5 seconds

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 4bar and flow rates up to 13 litre/min 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 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 4bar and flow rates up to 18 litre/min.
  • Elements are available with industry-standard tri-clamp sanitary fittings; and with Cam and Groove fittings for industry.

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 16 litre/min flow at up to 2bar pressure.
  • Tubing is available in eight materials for almost any chemical requirement.

  • 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. IP31 cased pumps for light industrial and wipe-down environments and IP66 cased pumps for washdown environments.
  • 630Du - IP31 and 630DuN - IP66 with configurable inputs and outputs, plus RS232 and RS484.
  • 630Bp - IP31 and 630BpN - IP66 Real time communication makes your process secure and flexible. Bus speed 9.6 kbits/s up to 12000 kbits/s connectivity
