Standard chemical pumps of the siHl'SOc',em range are horizontal single-stage volute casing pumps with dimensions to ISO 2858 / EN 22858. They meet the It is a modular configuration of either bare shaft end or close-coupled design. Shaft sealing options are single or double acting mechanical seals, magnetic drives or canned motor designs. The benefits are the interchangeability of the back pull-out assemblies and a reduction of spare parts Pumps of the siHl'SOc',em range meet the requirements food processing plant engineering and construction. The siHl'SOc',em hydraulics can be designed either with a closed impeller or a semi-open impeller. The shaft seal chamber of the back pull-out assemblies can accommodate all usual mechanical seal types (single or double acting mechanical seal to ISO 3069/DIN 24960, cartridge mechanical seals, gas Close coupled pumps are furnished with standard Leak-free back pull-out assemblies with magnetic drive or canned motor meet the requirements with regard to job safety, operational reliability and environmental protection. Magnetic drive isolation shroud materials are Hastel- Technical data Casing pressure: Shaft seal: - mechanical seal - magnetic drive - canned motor clockwise, when viewed from Temperatures up to 400 °C without external Special materials Heating of all casing components that come into contact with the fluid handled Monitoring systems
