Across International Variable Flow Peristaltic Pumps

Precision Fluid Transfer Based on Biological Principles

Peristaltic pumps, also known as roller pumps, represent a highly reliable type of positive displacement pump used for pumping a wide variety of fluids with exceptional accuracy and contamination-free operation. The Across International P04M, P2A, P6A, and P12M series utilize the same peristaltic principle found in biological systems like the gastrointestinal tract, where fluid is contained within a flexible tube fitted inside a circular pump casing. As the rotor turns with attached rollers, shoes, or lobes, it compresses the flexible tube, pinching it closed to force fluid movement through the tube while simultaneously inducing flow as the tube returns to its natural state after compression passes. This elegant mechanism traps bodies of fluid between multiple rollers and transports them at ambient pressure toward the outlet, providing gentle, pulse-free fluid transfer ideal for sensitive applications. Available in four capacity configurations—P04M (0.4L/min), P2A (2.3L/min), P6A (6L/min), and P12M (12L/min)—these pumps operate with maximum rotation speeds up to 600 rpm (P2A, P6A, P12M) or 100 rpm (P04M) with precise 0.1 rpm step control, accommodating tubing sizes from 1/2" to 5/8" depending on model.

Advanced Control Systems with Universal Voltage Compatibility

All models feature auto-intelligent voltage recognition for 110V-230V operation at 50/60Hz, eliminating the need for manual voltage switching and providing global compatibility for international laboratory environments. The P2A and P6A models incorporate sophisticated color LCD touchscreen controllers offering advanced distribution programming (0 to 9999 cycles), precise distribution timing (0.1 second to 9999 minutes), and adjustable distribution intervals, while the P04M and P12M utilize analog controllers for straightforward operation. All pumps include fluid retainment capability through programmable pump roll-back (10 to 720 degrees at 1-degree steps) with variable speed control (10 to 300 rpm), preventing dripping and ensuring accurate fluid dispensing. Standard features include remote on/off switches, with optional RS485, 0-5V, 0-10V, and 4-20mA communication ports enabling PLC control of pump start, stop, speed, and rotation direction—critical for automated laboratory processes and production environments. Power requirements scale appropriately from 22 watts (P04M) to 500 watts (P12M), while all models maintain IP31 protection rating and operate reliably in temperatures from 0 to 40°C with humidity below 80%.

ETL Certified Reliability for Continuous Operation

Engineered for demanding laboratory and industrial applications, the Across International peristaltic pump series delivers contamination-free fluid transfer since only the tube contacts the pumped fluid—never the pump mechanism itself. This design principle makes these pumps ideal for sterile applications, corrosive chemicals, viscous fluids, and sensitive biological samples where cross-contamination must be completely eliminated. The pumps may run continuously for extended periods or be indexed through partial revolutions to deliver precise smaller fluid volumes, providing exceptional versatility for applications ranging from chemical dosing and pharmaceutical production to bioprocessing and analytical chemistry. Each model is ETL tested to UL and CSA standards, ensuring compliance with North American safety requirements and providing confidence for critical laboratory operations. Compact dimensions ranging from 150×300×190mm (P04M) to 230×460×230mm (P12M) allow flexible installation in space-constrained environments, while robust construction with weights from 4.5 kg to 9 kg ensures stable operation. Standard tubing models are specifically matched to each pump configuration (TP04M.XF, TP1M.XF, TP6A.XF, TP12M.XF), with compatible pump heads (Y15, K25, Y35) optimized for reliable long-term performance across diverse fluid transfer applications.
