SP/SMT 1 Flow Divider with and without inline strainer for circulating-oil or hydraulic systems Introduction The flow divider splits the supplied flow into two equal induvidual flows or into two individual flows in a specific ratio. Advantages • Compact design, for installation near by • Can be used with a wide range of • Large selection of different flow divider • Self-regulating, so varying back pressures • Inexpensive monitoring since the pres- have negligible impact on dividing accuracy • Easy flow adjustment by changing nozzles • Defined dividing ratios sure balance also closes the second outlet port if one of the outlets is blocked. An upstream pressure switch or volumetric flow controller thus controls 2

Flow Divider SP/SMT 1 Flow divider design Design of the SP/SMT1 flow divider The flow divider is distinguished by its simple and compact design. Inside the flow divider’s housing there is a control piston, also called a pressure balance. It holds the two nozzles d1 and d2 (DF and DF´). Functional diagram of the SP/SMT1 flow divider Pressure po is applied to the two nonadjustable orifices DF and DF´ at the inlet P. (these are the two exchangeable nozzles d1 and d2). The control piston compares the pressures p1 and p1´. The control piston drifts out of its center position when p1 ≠ p1´....

Flow Divider SP/SMT 1 How to select the right flow divider A flow divider splits the supplied flow into two equal individual flows or into two individual flows in a specific ratio. The following specific values must therefore be known to define the right flow divider: • required flow Q1 for lube point 1 • required flow Q2 for lube point 2 • Operating viscosity of the lubricant to be Problem Two lube points should be supplied with oil. The oil flows should be divided as follows: • Lube point 1 with Q1 = 250 cm3/min • Lube point 2 with Q2 = 750 cm3/min. The operating viscosity is 650 mm2/s...
