NMVN / GVN / SVN / SKVN PUMPED MEDIA Clean water, boiler feed water, condensate and cooling water (NMVN and GVN); clean water and waste water in the low-pressure range (SVN and SKVN) MATERIALS In grey cast iron, cast steel or cast stainless steel according to the requirements of the pumped medium. Special materials are possible. TECHNICAL DATA • Performance data The maximum delivery values, such as flow rate and head, depend on the pump design, speed, installation length, and other factors. Please contact us for more information. You will then receive our offer for an optimally designed pump. • Shaft seal According to customer requirements or the requirements of the pumped medium by stuffing box packing or mechanical seal. If the pumped medium allows, pumps with a side- mounted, elevated discharge pipe can be operated without a shaft seal. • Lubrication Plain bearings are lubricated by the pumped medium, by grease via an automatic grease pump, or by fresh water. The rolling bearing in the motor bracket is lubricated with grease or oil. • Special versions For many of the pumps we supply, we have implemented our customers’ requirements for special materials and customised designs. Multi-stage high-pressure pump as a barrel pump: Q max. 400 m³/h, H max. 400 m 45
