MOTOR DRIVEN METERING PUMPS

MOTOR DRIVEN METERING PUMPS - Introduction

Motor Driven Metering pumps belong to the family of alternating volumetric pumps. Motor dosing pumps are recommended when high performances are required and feature the following basic elements:

Gearbox in cast aluminium protected with Epoxy paint. The gearbox mechanism is operated by an eccentric cam, which provides a positive displacement delivery stroke, whilst the suction stroke is spring assisted.
Adjustable capacity from 0-100% whilst in operation or at rest. Flow rate is adjusted by a micrometer screw to control stroke length (10:1 ratio).

Maximum suction lift 4 metres with water.
Motor and gearbox coupled by means of a flexible motor coupling, thus increasing transmission life.

Each pump is individually tested and all units are CE certified

MOTORS FEATURES
	Standard power supply: 230/400 Vac 50 Hz / 275/480 Vac 60 Hz; 3 phase,+/-10%. Standard motors are vertical mounting “TEFC, B14 type, flanges IEC 60072 Conform with IP55 protection. Isolation class F, others available upon request. Motors are TEFC vertically mounted, ~ 1400 rpm Other power supply upon request: • 230 Vac 1 phase 50 Hz or 60 Hz () • 110 Vac 1 phase 50 Hz or 60 Hz () (•) NOTE: at 60 Hz frequency, motor speed and thus stroke rates and flow rates increase by approx. 20%. 60 Hz are only available for pumps with 60 and 103 strokes per minute.
