10 Operating parameters
The following tube materials can be used with the 501RLA pumpheads. Bore sizes range from 0.5mm to
8.0mm, with an option of 1.6mm or 2.4mm wall thickness:
Tubing: working temperature range
Marprene 5C to 80C (41F to 176F)
Bioprene 5C to 80C (41F to 176F)
Pumpsil -20C to 80C (-4F to 176F)
GORE® STA-PURE® Pump Tubing – Series PCS 0C to 80C (32F to 176F)
GORE® STA-PURE® Pump Tubing – Series PFL 0C to 80C (32F to 176F)
Neoprene 0C to 80C (32F to 176F)
The following parameters define the boundary of the safe working envelope - these values must not be
exceeded (ATEX compliance will be invalidated):
501RL ATEX pumpheads (all model variants)
Ambient temperature range 5C to 40C (41F to 104F)
Maximum allowable fluid temperature 65C (149F)
Max peak pressure (0.5 to 4.8mm bore) 2 bar (29 psi)
Max peak pressure (6.4 to 8.0mm bore) 1 bar (14 psi)
Max continuous speed 300 rpm

Tube life section 11 "Tube life" on the next page
WARNING! Do not run dry for excessive periods. Roller and tubing
temperatures can exceed normal operating range.
Tube life will be reduced increasing the chance of premature failure.
WARNING! Do not run pumphead against a dead-end condition
(closed discharge). This can lead to excessive roller and tubing
temperatures and pressures in excess of the limits in the table above.
Tube life will be reduced increasing the chance of premature failure.
