Dong Il Ent products

This product is steady seller like books. Since launching the product in 1993. there has been no revision of product design. The reason is it doesn`t need to. It is wonderful product design so that there are no defect and malfunction at all. If operator maintain well, it should works above 10 years. The motor is 3 phase. 220/380v. The type is diaphragm metering pump. According to fluid type, material of head can be changed such as PVC. SUS304, 316. TEFLON, PVDF. The range of capacity is from 50cc/min to 35000cc/min. but attach the head one more in parallel, capacity might be double.

Stable discharging precision; Completely leak proof glandless pump by high precision plunger.  Reallized compect & low pump. For the first time at pump head part introduced mass productsion technique including mechanism of oil pressure part and drive par for realization of stable quality and low cost. Reliable high hydravlic mechanism. Developed by Dong-il technique where has been acknowledged to process pump. It`s not. only compect type but also reliable high oil pressure mechanism. Excellent durability of pump`s drive part. Used cam mode reducer compect and steady reliable high worm gear type And complete airtight oil base lubrication mode. So it`s not only installed outside of building but also showing excellent durability at long continuous outside of building but also showing excellent durability at long continuous

This flat valve type pump has the best efficiency for sludge discharging. • Simple. Economic Vertical type Metering pump by rationalis tic design. Simlified using maintain and main tenance by compact design.
DF Series is can be as sembled duplex heads. 

Simple. Economic Vertical type Metering pump by rationalis tic design. Extremely good life by long operation. Can be injected small volum of liquid with accuracy/ (Tolerance limits: ±1 %). Can be done transporting injection by high pressure (Pressure limits : 150 kg/cri Max.). The range of effective adjustment stroke: 20% - 100%). Using temperature : OC ~ 100*C.
