Larox Flowsys” new three-inch LPP produces the highest flow per compression of any hose pump, according to the company. In almost all cases, a one size smaller Larox LPP pump can be used compared to a shoe design or double-compression design peristaltic pump. The Larox LPP family of pumps has a unique 360-degree elliptical rolling design, which creates virtually no heat, low hose stress, low energy consumption, and long hose life. Pump sizes are ½”, ¾”, 1”, 1.5”, 2.5”, and 3”. The Larox family of pumps have a flow range of .4 GPM to 176 GPM. In almost all cases, Larox says its pumps can run at more than two times the RPM and still produce more than four times longer hose life than conventional shoe design or double-compression per revolution pumps. The yearly savings (Larox compared to shoe or double compression design hose pumps) in spare hoses, energy consumption, glycerin consumption, and maintenance costs are often as much as the cost of two pumps, according to Larox.
