Side Channel Pumps Self-priming, vertical type DRV 0201 . . . 0401 Sterling Fluid Systems Pumping Technology DRV-00 / 2003 Technical data Capacity: from 0,04 up to 2 m³/h Delivery Head: from 1,5 up to 27 m Speed: 1450 rpm (max 1800 rpm) or 2900 rpm (max. 3600 rpm) Temperature: max. 100° C Casing pressure: PN 6 Shaft sealing: stuffing box or standard mechanical seal Flange connections: female British standard pipe thread (BSP) Direction of rotation: clockwise (when seen from the drive end) Application The Sterling SIHI DRV pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. The DRV pumps are used when clear or turbid liquids with an aggressive nature, in varied concentration and temperature ranges and without any abbrasive particles, are to be handled reliably and trouble free. The performance curve steepness admits a precise regulation of the pressure with a small change in capacity. Their applications cover the private, professional and industrial fields. For example: • Domestic plants and agriculture for feeding spring well fountains and for garden and lawn cultivation. • Trade and industry for handling coolants, for sampling and chlorination processes in waterworks, for running bottle washing machines or for circulating buffer water in big centrifugal pumps. • Chemical and pharmaceutical industry for laboratory techniques or in the food industry. Design Single stage, vertical side channel pump with an open vane wheel impeller. The program comprises 3 sizes. Because of the vertical arrangement of the unit, the floor space requirements are low. If the pipelines are of sufficient stability, the units of this series can even be suspended in the piping system without any foot support . Construction Casing pressure Maximum 6 bar from 0 °C up to 100 °C. Please observe Technical rules and safety regulations: Casing pressure = inlet pressure + delivery head at minimum pump capacity. Position of branches Horizontal suction and delivery branch on opposite sides of the pump. Flanges The flanges are suited with female BSP thread (inches). Bearings Two grease lubricated ball bearings according to DIN 625 (design B) or two liquid surrounded sleeve bearings (design F). The first grease filling is done in the factory. Direction of rotation Clockwise, when looking at the pump from the drive end. Shaft sealing The shaft can be sealed by of a stuffing box or a standard mechanical seal.
