SOLH PB1011A miniature diaphragm pump is fully interchangeable with equivalent SMC PB1011 models. The integrated built-in DC24V 3-port solenoid valve enables direct electric control, while PB1013A air pilot variant is designed for external equipment interlock. Shaftless-seal construction eliminates medium leakage entirely. Wetted components are optional PP polypropylene or SUS316 stainless steel, paired with composite PTFE diaphragms and FKM seals for excellent resistance to weak acid, alkali and organic solvents. It delivers adjustable flow from 8 to 2000 mL/min, handles liquid viscosity up to 100 mPa·s with maximum 2.5 m dry suction lift, operates below 64 dB(A) noise and achieves 30 million cycle diaphragm service life. Fluid ports adopt standard Rc1/8 thread with optional NPT1/8; air supply & exhaust ports use M5 miniature threads. Installation requires liquid outlet facing upward to avoid air lock. Widely used for micro chemical liquid transfer in semiconductor & PV lines, medical biochemical reagent feeding, printing ink & glue supply, and precise chemical dosing for environmental water treatment equipment.

The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage. It serves as a crucial protective and control unit for power distribution equipment and industrial facilities. This circuit breaker is suitable for environments that require frequent operations at the rated current or the capability to interrupt short-circuit currents multiple times. The circuit breaker features a modular design, where the operating mechanism and the circuit breaker body are separable, allowing for quick replacements and assembly. VSG vacuum circuit breaker is a new indoor switchgear. It is mainly used for three-phase AC power system with rated voltage of 12kV and rated frequency of 50-60HZ. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plants, steel mills, metallurgy, petrochemical, transportation, buildings and other industrial and mining enterprises. As a switchgear for protecting high-voltage motors, transformers, line faults and other loads.
