Overview

Among all L/S pump heads, the pump head with the highest flow rate and pressure has a larger suction stroke, which can transmit fluids with higher viscosity. The pump tube has a longer service life under pressure conditions of up to 10.3 psi. The pump tube is designed with the same side inlet/outlet, and the pump head can be installed upright or sideways. The rollers, bearings, turntable, and shaft are all made of stainless steel (SS) material; The bite bed is made of polyphenylene sulfide (PPS) - both SS and PPS have excellent chemical resistance. It can match all L/S drivers in this catalog that can connect two or more pump heads (high-efficiency pump heads cannot be stacked). It is compatible with all four sizes of high-efficiency precision pump tubes: L/S 15, L/S 24, L/S 35, L/S36, as well as our high-pressure pump tubes: L/S 14HP, L/S 15HP, L/S 16HP, and L/S24HP.
