• When bending the tube, provide sufficient leeway in the bending so that the tube will not break. Also ensure that it will
not be rubbed against or trodden on.
• Insert the tube firmly so that it will not become disconnected, and tighten the cap nuts securely. Do not excessively
tighten the cap nuts. Doing so may damage or break the joint.
• If the temperature of a liquid or ambient temperature is higher than room temperature, the tightening force will be
reduced, and the tube may become disconnected. After operation has started, tighten up the cap nuts as appropriate.
• When tightening the cap nuts, hold the tube to prevent it from being twisted. The joints and other areas may be loos-
ened by the return force of the tube.
• The pump comes with a 3-meter long tube for both the discharge side and suction side. When longer tube is used, the
pressure loss may exceed the pump’s maximum discharge pressure so thicker tube will be required. Provide details
on the (1) viscosity of the liquid, (2) length of the pipes (how they are positioned) and (3) specific gravity of the liquid
to a TACMINA representative who will select the appropriate tube size.
• When disconnecting the tube for jobs such as maintenance and then afterwards re-connecting the same tube, cut
about 10 mm off the end of the tube before re-using them.
