MARKINGS The manufacturer is required to apply the following markings: Products shall be marked with the markings specified by the particular product standard. Products certified for Canada shall have all Caution and Warning markings in both English and French. Additional bilingual markings not covered by the product standard(s) may be required by the Authorities Having Jurisdiction. It is the responsibility of the manufacturer to provide and apply these additional markings, where applicable, in accordance with the requirements of those authorities. The products listed are eligible to bear the CSA Mark shown with adjacent indicators 'C' and 'US' for Canada and US (indicating that products have been manufactured to the requirements of both Canadian and U.S. Standards) or with adjacent indicator 'US' for US only or without either indicator for Canada only. All markings required by CSA must be permanent and legible. Devices or components shall be labeled in a manner to ensure that all markings are visible after installation. Where it is not practical to place the markings directly on the device, component or material, the markings shall be located on the container or packaging and/or literature accompanying the device, component or material. The content consists of: manufacturer's identification: 1996 or DAB Pumps ; o in addition to the manufacturer s identification may be branded as Grundfos ; CSA Mark with "C", "US" indicator; qualifiers "Drinking Water" (optional) and "NSF/ANSI 61" below or adjacent the CSA Mark; qualifiers NSF/ANSI 372 or "LLC" or "LOW LEAD CONTENT" below or adjacent the CSA Mark; product identification (if applicable) DQD 57 Rev Page 2

6 NKV MUTISTAGE CENTRIFUGAL ELECTRICPUMPS WITH VERTICAL AXIS TECHNICAL DATA Operating range: from 18 to 15 gpm with head up to 834 ft. Pumped liquid: without solid or abrasive substances, not viscous, not aggressive, not crystallised and chemically neutral, close to water characteristics. Liquid temperature range: from 5 F to 248 F. Maximum ambient temperature: 14 F. Maximum working pressure: 362 psi (25kPa) NKV Installation: fixed, vertical mounting. Special version on request: different voltage supply and anti-deflagrating version. Motor protection: IP 55. Insulation class: F. APPLICATIONS Vertical multistage centrifugal pump suitable for water systems of medium and large water utilities. It is suitable for pressurization units, boiler feed, hot water circulation, and cooling water, fire fighting and washing systems, supplying drinking water and feeding autoclave systems, irrigation and sprinkler systems and water purification. PUMP FEATURES NKV All the parts in contact with liquid are stainless and are approved to ANSI NSF61 for Drinking Water. AISI 34 microcasted stainless steel internal pump body, ULTEM diffusers, AISI 431 pump shaft, impellers and pump sleeve in stainless steel AISI 34. External pump body and support in cast iron cataphoresis coated. Cartridge mechanical seal silicon carbide/silicon carbide, exempt from maintenance, can be dismantled without removing the motor starting from 7.5 Hp (5.5 kw) Connected to the motor with a rigid coupling. MOTOR FEATURES Induction motor closed and cooled with external ventilation. Shaft with rotor mounted on oversized greased sealed-for-life ball bearings to ensure silent running and long life. Motor should be protected with a suitable overload protection complying with the regulations in force. Manufactured according to CEI 2-3. Standard voltage: Tri-phase /38-48 V / 6 Hz.
