H-Type Ceramic Valveless Metering Pump

H-Type Ceramic Valveless Metering Pump — Product Specification & Description

1. Product Overview

The H-Type Ceramic Valveless Metering Pump is a heavy-duty, high-pressure ceramic dosing pump designed for demanding fluid transfer, micro-dispensing, and continuous metering. The "H-Type" architecture features a reinforced drive assembly and high-rigidity structural frame paired with a valveless, rotating-and-reciprocating ceramic plunger. Engineered specifically for high-viscosity, high-pressure, or mildly abrasive liquids, it delivers pulse-free precision without internal check valves, dynamic packings, or elastomeric seals.

2. Key Features & Advantages

• Heavy-Duty High-Pressure Design: Reinforced mechanical drive structure enables stable metering at elevated working pressures up to $1.6text{ MPa}$ ($16text{ bar}$) without volumetric drift or mechanical deflection.

• Valveless Positive Displacement: Replaces traditional check valves with a single rotating-reciprocating ceramic plunger, eliminating valve clogging, jamming, and pressure-drop lag.

• High-Viscosity Capability: Efficiently handles thick liquids, gels, and filled slurries up to $30,000text{ mPa}cdottext{s}$ (cps) with minimal shear stress and consistent flow rate.

• Sapphire-Grade Ceramic Fluid Path: High-density Zirconia ($ZrO_2$) or Alumina ($Al_2O_3$) plungers and sleeves feature sub-micron clearance fits ($le 2,mutext{m}$), offering self-lubricating, non-galling, and wear-resistant performance.

• Superior Chemical Immunity: Inert ceramic wetted surfaces withstand aggressive acids, alkalis, solvents, and corrosive industrial slurries without metal ion contamination or surface erosion.
