Vario C Motor Driven Diaphragm Metering Pumps

ProMinent® Vario C pumps are designed for simple applications. They are espeically suitable for continuous metering.

Advantages

• Good suction capacity, smooth metering stroke and contantly exact metering
• High process quality: metering reproducibiltiy better than ±2 %
• Robust design: strong drive motor, shock and chemical resistant glass fibre reinforced plastic housing
• Good adjustment to defined applications thanks to 4 different gear reductions and 2 liquid end sizes in 2 materials

Application areas

• Time-controlled chemical addition in the cooling water circuit
• Continuous chemical addition in water treatment at constant volume streams

Features

• Capacity range 8 - 75 l/h, 10 - 4 bar
• Stable corrosion-resistant plastic housing with protection class IP65
• Stroke length: 3 mm, adjustable by means of self-arresting turning knob in 1% steps
• Liquid end materials: PVDF, Stainless steel 1.4571/1.4404
• Metering reproducibility at defined conditions and correct installation better than ±2 % (stroke length range 30-100%)
• Drive available with three phase ac standard motor or single phase alternating current motor (optionally)
