The Projet Meta pump is a durable and reliable motor-driven modular metering pump that can be combined with additional pumps to improve metering capabilities. There are two types of metering pumps: plunger type and mechanical diaphragm type. Advantages of Meta plunger motor-driven metering pump:

	High operational reliability: strong, reliable, and very durable
	High processing quality: plunger type repeated measurement accuracy better than ± 0.5%, diaphragm type better than ± 2%
	Modular design is easy to meet customer requirements and has a wide range of applications

Application areas:

In boiler water treatment, chemicals and additives are added in proportion

Characteristics:

	Piston type single pump head measuring range: 6-49 l/h, 240-27 bar
	Can be combined with dual pumps or triple pumps. If the back pressure is reduced, more additional pumps can be connected
	The stroke count of the additional pump is the same as that of the main pump
	Standard drive: Three phase motor 0.18 or 0.37W, 230/400V, 50Hz
	Protection level: IP 55 (optional ATEX-T3/T4); Insulation level: F
	Stroke length 0-15.5mm, adjustable step size 0.2%
	Set stroke length: manual (optional actuator or variable frequency drive)
	Optional variable frequency drive speed regulation, protection level: IP54
	Optional stroke sensor with NAMUR signal to record stroke, suitable for batch or proportional measurement
	Transmission case housing: cast iron with acrylic resin coating, resistant to seawater corrosion
	The material of the pump head is stainless steel 1.4571
	Oxidized ceramic plunger
	Under specified conditions and correct installation (stroke length between 10-100%), the repeated measurement accuracy is better than ± 0.5%
	The suction range varies with the density and viscosity of the medium, the size of the connecting pipeline, and the number of strokes
	Environmental temperature: -10 ℃ to+50 ℃
	Medium temperature: 0 ℃~+100 ℃
	Medium viscosity: ≤ 200 mPa. s (without valve spring); ≤ 500 mPa. s (with valve spring); ≤ 1000 mPa. s (designed and installed accordingly); ＞ 1000 mPa. s (after corresponding design and installation, and consulting with Prominent)

Meta diaphragm metering pump features:

	Measurement range: 40-1000 l/h, 12-3 bar
	The diaphragm is made of high-quality fabric reinforced EPDM (ethylene propylene diene monomer rubber) and is in contact with the medium using PTFE
	Motor power: 0.18, 0.37, 0.75kW, voltage 415V
	Pump head material: polyvinyl chloride, polypropylene, stainless steel or PTFE
	If automatic control is required, a motor speed controller or servo controller can be used to adjust the stroke length
