2 All about your flow Tapflo is a leading pump manufacturer with the ambition to provide a wide range of premium products for various industrial applications. We focus on delivering the best fluid processing solutions and support on all stages of the process, worldwide. About Tapflo Est. in Sweden 1980 Tapflo is an independent, Swedish, family owned, manufacturer and global supplier of air operated diaphragm pumps, centrifugal pumps and other industrial process equipment. The company was founded in Kungälv, Sweden in 1980 and has since then been working with design and manufacture of thermoplastic, metal and sanitary series diaphragm pumps and also with complete range of centrifugal pumps and industrial equipment. After years of dynamic development the company evolved into Tapflo Group with worldwide operations. Tapflo Group is represented by own companies and independent distributors all over the world on 6 continents.

This allows us to frequently offer solutions that are even more sustainable and efficient. 2

3 SEALING SYSTEMS Any type of machine with a rotating part in a fluid must prevent the inner environment containing the product and the outer environment coming in contact. To prevent this, various sealing systems were introduced, based on the type of machine, the process product, pressure, etc... that keep the two environments separate. Nova Rotors has developed experience over the years to offer clients optimal types and configurations, even customised, suitable for every type of application. The various seals can be identified and selected based on the pumped product. Various types of seals are available, from packing to cartridge mechanical and component seals. The latter can be selected in a wide range of configurations based on requirements, for example they can be balanced and unbalanced, multispring or with leaf springs, bellows, with protected springs, etc...; the housing, the elastomers and the faces that prevent process product passage can be selected in various materials. Diamond Industrial Series Diamond industrial pumps are manufactured with mechanical seals as they offer higher performance and reliability. On request, the version is also available with packing and flushed packing. Packing Seal B01 Standard packing seal with PTFE impregnated seals, at low friction coefficient per pack. Low cost installation solution Suitable to process products with suspended solids and abrasives. up to 2 bar for clean fluids; 0,5 bar for fluids with suspended solids. Packing Seal With Flushing B02 Packing seal with low friction coefficient rings and flushing rings. Flowing pressure must be from 0.5 to 1 bar over the pressure inside the casing and compatible with the process liquid. Suitable to process many abrasive products. up to 2 bar for clean fluids; 0,5 bar for fluids with suspended solids. 3

4 Single Mechanical Seal G0K9 Made of a stationary part and a rotating part, available with elastomer or metallic spring. Faces in contact with friction coefficient very low. Independent rotation direction. Suitable to process products with high viscosity and with small quantities of solids. Single Mechanical Seal + Quench Q0K9 In compliance with single mechanical seal specifications, the flow is not pressurised, making this seal suitable in pumps with an inverse rotation direction such as vertical pumps and in all those applications in which the product has solid, crystalline or abrasive residue. Double Mechanical Seal Back to Back D0K9 The faces are not in contact with the product. The flushed liquid must be compatible with the process liquid and it is necessary for flushing pressure to be over 1 bar compared to that of the body of the pump. Suitable to process products with solid, abrasive, aggressive and crystalline parts. Double Mechanical Seal in Tandem K0K9 Similar to a seal with quench. The difference is the type of seal. In a seal in tandem, the seals are two singles so that if one breaks, the second ensures the product seal of the product and enables work. Suitable for very aggressive and polluting products which if leaked cause considerable damage. 4

5 Diamond Hygienic Series Diamond hygienic pumps were designed in single mechanical seal configurations, therefore not including a packing assembly. The position was also reviewed of the seals, advancing them (if internal) and positioning them under the suction for complete engagement of the process product. A new seal configuration was also added compared to the previous Diamond Industrial Series, i.e. the external single seal is then emerged in the process product. Internal Single Mechanical Seal Composed of a stationary part and a rotating part. Positioned under suction for greater engagement of the pumped product. Faces in contact with friction coefficient very low. Independent rotation direction. Suitable to process products with high viscosity and with small quantities of solids. External Single Mechanical Seal The faces are not in contact with the product. Suitable to process products with solid, abrasive, aggressive and crystalline parts. Single Mechanical Seal + Quench Q0K9 In compliance with single mechanical seal specifications, the flow is not pressurised, making this seal suitable in pumps with an inverse rotation direction such as vertical pumps and in all those applications in which the product has solid, crystalline or abrasive residue. Double Mechanical Seal Back to Back D0K9 The faces are not in contact with the product. The flushed liquid must be compatible with the process liquid and it is necessary for flushing pressure to be over 1 bar compared to that of the body of the pump. Suitable to process products with solid, abrasive, aggressive and crystalline parts. EDouble Mechanical Seal in Tandem K0K9 Similar to a seal with quench. The difference is the type of seal. In a seal in tandem, the seals are two singles so that if one breaks, the second ensures the product seal of the product and enables work. Suitable for very aggressive and polluting products which if leaked cause considerable damage. 5

Silicon carbide - Metal Tungsten parts: carbide AISI 304 AISI 316 FPM EPDM NBR Mechanical Seal Series 110 type 110 Balanced mechanical seal with incorporated shaft sleeve, double directional with single leaf spring. Thanks to the geometry of the design, the spring never works in contact with the product, making it suitable for all uses with highly viscous liquids or those with suspended solid parts. Silicon carbide - Tungsten carbide AISI 304 AISI 316 F51 (Duplex) F55 (Superduplex) C-276 (Hastelloy) FPM EPDM NBR SILI- CONE FFPM PTFE Mechanical Seal Series 120 type Balanced and unbalanced (based on the type) mechanical seal, independent of the rotation direction, with a single leaf spring (multispring on request). Its versatile configurations enable its broad use not only on machinery with heavy use at medium pressure, but also in the presence of very viscous liquids. High resistance to torsion and compact axial size enable its universal application. Silicon carbide - Tungsten carbide - Graphite AISI 304 AISI 316 FPM EPDM NBR SILI- CONE FFPM PTFE 6

7 Mechanical Seal Series 170 type 172 Single mechanical seal, unbalanced, independent of the rotation direction with multispring configuration. It is a mechanical seal with reduced axial size. Thanks to the possibility of configuration with all the stationary rings it is interchangeable with the most widespread mechanical seals on the market. Silicon carbide - Tungsten carbide - Graphite - Aluminium oxide AISI 304 AISI 316 FPM EPDM NBR SILICONE FFPM PTFE Le tenute meccaniche a cartuccia Cartridge Mechanical Seal Mechanical cartridge seal engineered for the Diamond series. The various configurations enable use of a wide range of applications, from medium to heavy use. The fundamental advantage is the quick replacement and regeneration of the worn seal making it economically beneficial in the short to medium term. The single seal is available in configurations with quench, double back to back and double in tandem.
