Mechanical drive diaphragm metering pump
The main components of the DJD series diaphragm metering pumps are made by precision casting and CNC machining. According to the design of the liquid end structure, the pump does not leak during operation. The drive components are rugged and durable. There are various materials avaiblable for our dosing pumps, including stainless steel SS304, SS316, SS316L, 904L, duplex stainless steel CD4MCu, 2205, 2507, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
■Flow rate: 0～500L/H
■Discharge pressure: 0～1.2 Mpa
■Suction pressure: Max. 2 bar
■Working Temperature: -30ºC～90ºC
■Mechanical driving, easy operating with high accuracy
■Suitable for transferring all kinds of media
■Gear box material is high strength aluminum alloy or HT200 cast iron.
■With adjustable eccentric mechanism, we can ensure high repetition accuracy.
■Flow rate can be adjusted between 0% and 100% during shutdown or movement.
■Both manual variable speed and frequency variable speed are available.
■All moving parts are lubricated by oil to ensure low noise, high efficiency and long time operation.
■Hydraulic end can be equipped with single or double diaphragm and alarm system for diaphragm breakage
■Two or more pump heads (max. 6 heads) can be connected together. Different pump heads can be used to pump the same medium. Pulse will be decreased and capacity can be increased with the same motor pow0er. It can also be used as proportional pump to transfer
■Pump head: SUS304, SUS316, PVC, PTFE
■Valve: SUS304, SUS316, PVC, PTEF
■Valve ball: ZrO2, SiO, SUS304, SUS316, Ceramic
■Material of wetted parts can be PVC, PVDF, PTFE, HC and all kinds of stainless steel.
■It is widely used in petrochemical industry, environmental engineering, pharmaceutical, municipal, synthetic materials, paper making and food industries.
