RPB1011 Series Diaphragm Pump (PB1000A Built-In Solenoid Valve Type)

Brand: SOLH by Richge Technology

Product Positioning

     SOLH PB1011A belongs to PB1000A miniature single-acting pneumatic diaphragm pump series with built-in solenoid valve. It features compact outline, full corrosion resistance and zero shaft seal leakage. Designed for micro to medium flow delivery of chemical solvent, pure water, medical liquid and reagent, it is a compact precision dosing pump widely used in fine chemical, semiconductor and biotech industries.

Model Classification & Drive Mode

     --  PB1011A: Built-in integrated 3-port solenoid valve (DC24V), direct electrical signal control, plug-and-play wiring

     --  PB1013A: External air pilot type, driven by independent external solenoid valve

     --  Port size suffix: 01 = Rc1/8 standard fluid port

     --  Common complete models: PB1011A-01; PB1011A-01-B (with mounting foot bracket); PB1011A-01-N (NPT thread port)

Core Technical Specifications (PB1011A)

     -- Drive Unit: Built-in 3/2 solenoid valve, DC24V, power consumption 0.35W

     --  Flow Range: 8～2000 mL/min (0.12～120 L/h)

     --  Discharge Working Pressure: 0～0.6 MPa

     --  Dry Suction Lift: Max 2.5 m

     -- Operating Fluid Temperature: 0～50℃ (no icing inside pump chamber)

     -- Max Allowable Liquid Viscosity: 100 mPa·s

     -- Supply Air Pressure Range: 0.2～0.7 MPa

     -- Air Consumption: ≤40 L/min (ANR)

     -- Overall Dimension & Weight: 60×60×41 mm, approx. 170 g

     -- Operating Noise: ≤64 dB(A); noise further reduced with matched silencer

     -- Diaphragm Service Life: Up to 30 million switching cycles

Wetted Part Material Configuration

      -- Pump Body: Polypropylene PP / SUS316 stainless steel optional

     -- Diaphragm & Check Valve Core: Composite PTFE + PP

     -- Sealing Material: FKM fluoro rubber, outstanding resistance to acid, alkali and organic solvent

     -- Material Advantage: Shaftless seal design eliminates medium leakage; full corrosion resistance for chemical solution, pure water, medical reagent and mild acid/alkali fluid.

Working Principle (PB1011A Electric Control Type)

     -- Solenoid Energized ON: Compressed air enters drive chamber, pushes diaphragm to shift left; liquid inside pump chamber is discharged through upper one-way valve.

     -- Solenoid De-energized OFF: Drive chamber exhausts air; diaphragm resets rightward under built-in spring force; new liquid is sucked into pump cavity via lower inlet check valve.

     -- High-frequency solenoid on/off cycle (1～10 Hz) realizes continuous liquid suction & discharge; output flow can be precisely adjusted by changing switching frequency.

Installation & Piping Requirements

  1. Mandatory Installation Rule

     -- Fluid outlet port (OUT) must face upward to avoid air lock inside pump chamber causing flow interruption.

  2. Port Definition & Thread Spec

     -- Fluid IN / OUT main ports: Standard Rc1/8", NPT1/8 optional

     -- Air supply SUP port: M5×0.8 thread

     -- Exhaust EXH port: M5×0.8 thread, compatible with AN05-M5 miniature silencer

  3. Mounting Holes

     -- 2 × M4 screw holes with 6 mm depth; or φ4.5 through holes; dedicated foot bracket accessory KT-PB1A-5 available for fixed equipment installation.

Typical Industrial Application Scenarios

     -- Semiconductor & PV manufacturing: Chemical solvent transfer, cleaning liquid circulation loop

     -- Medical & biochemical equipment: Micro delivery of reagent, buffer solution and biological liquid

     -- Printing & packaging machinery: Ink, adhesive glue automatic feeding system

     -- Environmental protection & water treatment: Chemical agent dosing, waste water sampling collection

     -- General automation industry: Cutting fluid, cleaning agent and light oil conveying

Model Selection Guidelines

     -- Flow matching: Select PB1011A for flow ≤2000 mL/min; PB1013A air pilot model for special linkage control scenarios (max flow 1000 mL/min)

     -- Wetted material selection: PP pump body for general weak chemical liquid; SUS316 + PTFE combo for strong corrosive solvent

     -- Control mode: Electric direct control choose PB1011A; equipment external interlock linkage choose PB1013A air pilot type

     -- Auxiliary accessories: Install silencer on exhaust port to reduce running noise; match foot bracket for long-term fixed installation

SOLH Interchange Advantage

     SOLH-PB1011 series fully matches SMC original PB1011 series in overall dimension, port thread layout and all performance parameters, direct drop-in replacement without pipeline modification, with superior cost performance.
