We carried out the replacement of the mechanical seal of a vertical multistage Calpeda MXV 80 pump, using the BTS Engineering mechanical seal R-BT-RN3.NU 22, CAR/SIC, EPDM, 304.

Applications of Calpeda MXV pumps:

Pumping clean, non-explosive liquids without abrasive or fibrous impurities for use in domestic and industrial applications, in pressure boosting systems, fire-fighting installations, high-pressure washing equipment, irrigation systems, agriculture, sports facilities, etc. For operation in more aggressive conditions and media, we can offer mechanical seals made from alternative material combinations.

The rotary lobe Alfa Laval SRU pump (Sweden) is a reliable solution for pumping process liquids in the dairy, food, brewing, chemical and pharmaceutical industries, as well as in household chemicals and personal care applications. The pump is designed in accordance with the strictest hygienic standards and allows for Clean-in-Place (CIP) operation without disassembly.

It is an optimal solution for transferring various liquids — both low-viscosity media and creams, suspensions, emulsions, etc. (including those containing solid particles).

These pumps use R-AL.SR mechanical seals with Sinusoidal Wave Springs, featuring a compact working length, high reliability and long service life.

Applications of Grundfos CM pumps:

• Water supply
• Pressure boosting
• Water circulation in heating and air conditioning systems
• Pumping liquids in industry
• Freshwater fish farming
• Horticulture
• Agriculture

Technical specifications:

• Max. pressure, operating temperature: 10 bar
• Liquid temperature: from -30°C to +120°C
• Max. head (HMT): 18.5 m
• Max. flow rate: 303 m3/h

The Grundfos CM 150-350-260-30.0 480308 circulation pump is equipped with a mechanical seal type 2100S.

Thanks to its hydraulic characteristics and compact dimensions, the Dreno Compatta series manufactured in Italy is an optimal solution for pumping domestic wastewater. In the standard version, the shaft sealing is implemented by a lip seal on the motor side and a mechanical seal on the impeller side. The maximum permissible liquid temperature is 40 °C with the pump fully submerged.

When replacing the mechanical seal in the Dreno COMPATTA 4T pump, we used the pump shaft seal R-MG1 14, SIC/SIC, VITON, 304, D.

EBARA 3M pumps are mainly used for: water supply, pressure boosting, air conditioning, washing, irrigation, swimming pools, etc. In our case, the pump transfers brewing wort. A standard seal (GRAPHITE / CERAMIC / NBR) was used, which is not suitable for this medium (brewing wort). We replaced this seal with a BTS Engineering Ebara 3MHS mechanical shaft seal.

We offer the following types of seals for EBARA 3M:

• -10°C ÷ +90°C (standard mechanical seal): 364500000, 364500027
• -10°C ÷ +110°C for versions H, HS, HW, HSW: 364500001, 364500002, 364500039, 364500035, 364500036, 364500037

High-pressure pumps Fristam FPH and FPHP series are centrifugal, multistage pumps. They are designed for recirculation in reverse osmosis systems, with the possibility of adaptation to specific products, processes, and applications. FPH pumps can operate with inlet pressures up to 600 pounds per square inch, while FPHP models can operate up to 1000 pounds per square inch.

Fristam FPH series pumps are fully suitable for CIP and SIP.

The pumped liquid may be homogeneous or may contain air, gases, or suspended particles.

We replaced the mechanical seal Fristam FPH 1232/180 VA (18.5 kW), Article No. 0474540103, with the R-H7N mechanical seal.

We also replaced the mechanical seal of the FPH 3532/175VA 11 kW pump, Article No. 1802600289, with the R-H7N mechanical seal.

Single-stage end-suction pumps CNP series NISO, NIS, NISF are compact and easy to install. Thanks to the technological design, the bearing assembly with the impeller and sealing unit can be dismantled without disconnecting the pump casing from the pipelines. The pump is equipped as standard with a wear-resistant mechanical seal NISO-43/BSE4 728124298676 graphite/silicon carbide/EPDM.

In our case, this pump was used for pumping gasoline, so the seal was replaced with a more suitable one — R-BIA 43, CAR/SIC, VITON, 304, T1V.

The following mechanical seals are also available: NISO-33/BSE4, NISO-53/BSE4, NISO-60/BSE4, NISO-53/SWF14, NISO-33/WWF14, NISO-60/WWF14, NISO-33/SWE4, NISO-18/BSE4, NISO-33/WWE4, NISO-33/WWE4, NISO-33/BSE6, NISO-33/SSE6, NISO-43/SWE4, NISO-43/BSE6, NISO-43/SSE6, NISO-43/SWF14, NISO-43/WWF14, NISO-53/SWE4, NISO-53/BSE6, NISO-53/SSE6, NISO-53/WWF14, NISO-60/SWE4.
