Single Liquid Screw Valve
Product Description

Engineered for Stable Liquid Delivery

The structure is combined with rotor and the stator. The liquid in the closed space is transported forward by the rotor rotation. When the rotor rotates continuously in the stator cavity, it moves smoothly and uniformly from the suction end of the pump to the discharge end due to the action of pressure, thus completing the stable delivery of the liquid medium.

Key Features

Advanced screw valve technology for precise and reliable dispensing.

01

Constant Output Flow

Output flow constant, smoothly, pulsation-free and low shear for consistent dispensing results.

02

Accurate Measurement

Flow error < 1%, repeatability > 99% for precise and repeatable dispensing operations.

03

Ultra-Micro Flow

Especially suitable for various ultra-micro flow occasions, minimum trace amount can reach 0.001mL.

04

High Viscosity Compatible

Suitable for all kinds of high viscosity, high solid granular fluids, up to 8,000,000cps.

05

Stable Output

Output flow is proportional to rotational speed, unaffected by medium viscosity, pressure, or temperature.

06

Anti-Dripping Design

Forward and reverse rotation can be adjusted freely, perfectly avoids liquid dripping and drawing.

07

Simple Structure

Easy to disassemble, easy to clean, easy to assemble for convenient maintenance.
