External-gear pump MPD025

for food productswith DC motorstationary

Product Overview
MPD025 micro gear pump driven by a brushed DC motor. Designed for low-displacement, low-pressure applications with typical flow up to 2.5 LPM. Outlet pressure resistance indicated on the product page: 0.5–5 bar (see configuration-specific table for exact values).

Key Features

• Low Pulse
  Internal gear design provides continuous, steady fluid transfer with minimal pulsation.
• Compact Size, High Flow
  Suitable for equipment with limited space that require relatively high flow rates for the pump size.
• Cost-effective
  Brushed DC motor option supports simple construction and lower production cost.
• Simple Speed Control
  Motor speed and direction can be controlled by voltage regulation for straightforward system integration.

Product Description
The MPD025 is a miniature external gear pump with a DC brushed motor. Typical materials include SS316L machined casing (304 or PPS options depending on model), PEEK gears, FKM (fluorine rubber) sealing ring and dynamic shaft seal. Compact structure with adjustable flow via motor voltage. Applications include food dispensing, packaging and filling machines, vending equipment, food processing and cleaning systems.
