Explosion-Proof Precision Oil Pump Metering Assembly for Industrial Fuel and Chemical Transfer

High-Precision Explosion-Proof Oil Pump Metering Assemblies
This series of oil pump metering assemblies is engineered for accurate and reliable liquid transfer in demanding industrial environments. Featuring both vane pump and centrifugal pump designs, these assemblies deliver precise flow rates ranging from 140 L/min up to 700 L/min, with consistent metering accuracy between ±0.3% and ±1%. The combination of high-quality construction, robust motors, and explosion-proof certification ensures safe and efficient operation in flammable or hazardous conditions.

Flexible Power Options and Versatile Installation
The metering assemblies are available with AC220V 50Hz, DC12V, or DC24V power supplies to meet different industrial requirements. Vane pump models provide vertical suction distances of 3–5 meters, while centrifugal types efficiently handle horizontal delivery up to 15 meters. Motor power ranges from 1100W to 4000W, supporting both light and heavy-duty liquid transfer tasks. Compact dimensions and moderate weights—from 40 to 80 kilograms—allow easy installation and integration into industrial systems.

Reliable Construction for Industrial Liquids
Each assembly is made from high-quality materials capable of withstanding prolonged operation under challenging conditions. The components ensure low maintenance, long service life, and stable metering performance. These metering assemblies are suitable for fuels, chemicals, AdBlue, diesel, and other industrial liquids, providing consistent flow and accurate volume measurement in production, storage, or transfer applications.

International Recognition and Multilingual Naming
To support global markets, these pumps are known under multiple international names, helping clients identify and select them quickly:
English: Vane Pump Metering Assembly / Centrifugal Oil Pump Metering Assembly
French: Ensemble de Mesure Pompe à Palette / Pompe Centrifuge
German: Flügelzellen-Pumpen-Messvorrichtung / Zentrifugalölpumpen-Messsystem
Spanish: Ensamblaje de Medición de Bomba de Paletas / Bomba Centrífuga
Vietnamese: Bộ Bơm Đo Bằng Bánh Răng / Bơm Ly Tâm
Thai: ชุดปั๊มวาล์ววัดปริมาณ / ปั๊มแรงเหวี่ยงวัดปริมาณ
Indonesian: Rangkaian Pompa Metering Vane / Pompa Sentrifugal
