PERFORMANCE RANGE flow rate up to 500 I/min.(30m3h) dynamic head up to 12 m OPERATING LIMITS maximum operating depth 5m below water level maximum fluid temperature 50°C maximum passage for suspended solids ?50 mm Submersible high efficiency single vane pump for professional use.Built completely in stainless steel and oversized,extremely reliable and suitable for continuos heavy duty service. WORKING PRINCIPLE The MVS 10-1 SINGLE VANE PUMP is designed for automatic use(sihgle phase version).The operating principle is that of pumps with a single vane impeller. This is mounted on the end of the drive shaft and enclosed in a large ring chamber, formed by the pump body and the base.The suction opening is in direct with the liquid to be pumped.The rotating impeller transmits kinetic energy to the liquid, which is centrifuged in the ring chamber,where part of the kinetic energy is transformed into pressure energy.The particular shape of the impeller optimizes efficiency. PUMP INSTALLATION AND APPLICATIONS The MVS10-1 submersible pump is designed to handle dirty water and sewage in domestic and civil applications.It is fitted with a stainless steel single vane impeller,and is suitable for pumping liquids containing suspended solids,including short fibres.It is particularly recommended for the transfer of domestic sludge, refluent and surface water, water mixed with mud in areas such as: domestic housing, industrial applications and underground car parks. This pump is particularly dependable in fixed installations intended for automatic use.A purposely built pit with minimum dimensions 500x500x500 mm is recommended for fixed installations,to give total drainage,and to allow correct operation of the automatic float switch.This system (standard equipment on the single phase pump) automatically starts the pump when the fluid reaches a preset level.stopping it once the fluid has been emptied. PERFORMANCE The MVS10-1 pump has the following feature: a performance curve with particulariy high delivery rates.
