Impeller pump SP 25

waterfor chemicalselectric

The SP 25 pump is designed for transferring liquids containing impurities up to 3 mm in size. Its hydraulic components, including the impeller and nut made of PBT, and the cast iron pump body, make it suitable for use with water, emulsions, and oily substances with a viscosity not exceeding 21 cSt (3° Engel). The liquid temperature should not exceed 70°C. Common applications include: - Machine tools (milling-lathes) - Glass processing machines (TRI version) - Surface treatment plants - Filtration systems Installation: The pump should be installed on a tank with a capacity proportional to the flow rate, about 3-4 cm from the bottom. Ensure the maximum liquid level in the tank remains 3-4 cm below the support flange. For particularly dirty liquids, it is recommended to construct the tank with compartments to allow sludge to settle before being pumped out.
