Product Description

1. Product Introduction

Dongkai is a leading China Precision Hydraulic Diaphragm Metering Pumps manufacturers, suppliers and exporter. When Precision Hydraulic Diaphragm Metering Pumps run, your just requires only minimal maintenance. The diaphragms are durable and provide consistently accurate metering. The technology also offers a very high standard of safety: there is a pressure relief valve in the hydraulic end as protection against overload. The multi-layer diaphragms are equipped with a diaphragm rupture warning system as standard. So you can be sure that the feed chemicals cannot mix with the hydraulic oil.

2.Product Parameter (Specification)

Precision Hydraulic Diaphragm Metering Pumps DKY1.6/DKY3.0 Series Hydraulic Diaphragm Metering Pump Capacity range 8.6-1000lph ,5-500bar. Power: 0.37-1.5kw ，380V 3 phase on standard, single phase or other voltage on request; EX-proof motor is available on request.

3.Product Feature And Application

It consists of three main devices: (1)driving device, (2) adjusting device, (3) liquid delivery device. The crankshaft which reduces motor rotation speed by worm and worm gear makes the piston reciprocate in the hydraulic oil chamber. This reciprocating movements of the pitston make the PTFE diaphragm and the liquid which is isolated by the diaphragm sucked and discharged. Each pump is with internal pressure relief valve protecting pump from over pressure conditions.

The flow rate can adjusted via uniqe adjusting mechanism from 0-100%. The adjustiment can be carried when pump is in operation or at stop. The steady sate accurancy is ±1% from 30%-100% of the maximum output. Automatic operation is achived by variable speed drive.

Dongkai Accurate hydraulic diaphragm pumps are suitable for crossive,vaporing, flammable, explosive or toxic solutions. It can also transport suspended liquid or moderately viscous liquid.

Double diaphragm with diaphragm rupture detecting system is availble to prevent accident caused by mixture of hydraulic oil and the liquid after diaphragm ruptures.

The industries in which accurate hydraulics technology is used: Oil/gas production (onshore/offshore) Refineries Chemical / petrochemical industry Pharmaceuticals & cosmetics Food production Packaging industry (bottling pumps)
