ZL112 Series Multi-Stage Vacuum Ejector

Brand: SOLH by Richge Technology 

Product Positioning

     SOLH ZL112 series is an integrated multi-stage venturi vacuum ejector fully interchangeable with SMC equivalent models. It features ultra-high vacuum degree, large suction flow and drastically reduced air consumption. Multiple optional integrated modules are available including solenoid supply/release valves, vacuum pressure gauge, digital display meter and vacuum pressure switch. It serves as the core vacuum unit for automated robotic arms and multi-suction cup fixture systems.

  2. Standard Base ZL112 Series (Mechanical / Digital Gauge Optional)

Core Product Advantages

  1. Multi-stage venturi energy-saving technology

     -- Stable vacuum degree -88 ~ -92kPa, powerful suction flow; air consumption reduced by over 40% compared with single-stage ejectors, greatly lowering workshop compressed air cost.

  2. Highly modular integrated all-in-one design

     -- Optional built-in supply solenoid valve, vacuum release blow-off valve, silencer, digital/mechanical vacuum gauge and pressure switch. No extra separate accessories required, saving cabinet space and simplifying wiring layout.

  3. Low noise integrated silencer

     -- Built-in muffler structure limits running noise ≤70dB(A), friendly for indoor continuous workshop operation.

  4. Maintenance-free long service life

     -- Zero internal moving mechanical parts, resistant to frequent continuous cycling, supports 24-hour non-stop mass production operation.

  5. Multi-suction cup centralized vacuum supply

     -- Suitable for multi-jig multi-workstation synchronous adsorption, compact size allows direct mounting at robotic arm end effector to shorten vacuum pipeline response time.

Typical Industrial Application Scenarios

     -- Automated robotic grippers, multi-cavity suction fixture handling

     -- 3C electronics, glass panel, sheet metal, porous workpiece vacuum picking & placement

     -- Packaging, printing and food industry vacuum transfer equipment

     -- Leakage-prone workpieces and production lines requiring large stable vacuum flow

Step-by-Step Quick Selection Guide

  1. Confirm automatic vacuum control demand

     -- Only vacuum generation without auto blow-off: Select basic ZL112A / ZL112 bare model (external valve needed)

     -- Auto suction + quick vacuum blow-off recommended: K1 dual valve variant

     -- Cost priority simple suction only: K2 single supply valve variant

  2. Confirm vacuum monitoring signal requirement

     -- PLC threshold feedback required: Choose DNL (NPN) / DPL (PNP) vacuum pressure switch model

     -- Local visual pressure reading required: D digital display meter or G mechanical analog gauge

  3. Confirm exhaust layout requirement

     -- Standard indoor noise control: Standard version with built-in silencer (blank exhaust code)

     -- High flow / centralized main exhaust pipeline: P ported exhaust variant

One Sentence Summary

     SOLH ZL112 multi-stage venturi vacuum ejector delivers -88~-92kPa high vacuum with 40% lower air consumption, supports dual/single integrated solenoid valves, digital/mechanical vacuum gauge and NPN/PNP pressure switch options, the integrated compact vacuum module for robotic multi-suction cup automated handling systems.
