An Example of Success Using a Stainless Steel Magnet Drive Pump for Transfering a Slurry in a Petrochemical Plant

Use of stainless steel magnet pumps that can transfer slurry in a petrochemical plant.

A seal-less and completely leak-free magnet drive pump do not cause any leakage at all leaving the environment clean.

Outline

Introduced products MDS
Stainless steel magnet drive pump that can transfer a high density slurry liquid
Reaction liquid transfer pump (salt slurry of 10wt% to 15wt% is generated after the reaction)

Comparison between before and after installing a magnet drive pump

A double mechanical seal was used in the existing slurry pump. However, liquid leaks from the shaft seal occurred frequently. Then we decided to use three MDS stainless magnet pumps that can transfer a high density slurry.

Example of Using a Magnet Drive Pump to Transfer Detergent for CIP

Use of magnet pump for tranferring detergent in CIP (Cleaning IN Place)

The system removes stain adheres inside by the pressure generated by transferring detergent using the pump.

Outline

Introduced Products MP
Temperature of Liquid Alkali liquid (caustic soda) up to 48%
Acid liquid (nitric acid) up to 60%
Application Magnet pump to transfer detergent for CIP

In food manufacturing processes, every part of the facility need to be washed, including pump and piping, as well as the manufacturing facilities. CIP (Cleaning In Place) does not require disassembly and manually washing the equipment as was done before. The pump transfers detergent, while removing the dirt in the equipment by the pump pressure.

Sanwa magnet pumps are used in a CIP process. The detergents that are used are hazardous liquids such as alkalies caustic soda and nitric acid.
The various advantages of the Sanwa magnet pumps shown below were evaluated and our pumps are used because they do not leak hazardous liquids and ensure corrosion resistant against these liquids.

Introduced Products MP
Temperature of liquid high temperature water (100 to 150˚F)
Application Magnet drive pump SIP
MP_img_01

Fresh milk from a farm becomes processed milk after several processes including sterilization. During the high-temperature sterilization process using a heat exchanger, the temperature of hot water reaches up to 150˚F with the pressure of 0.4 MPaG.
Sanwa’s stainless steel magnet drive pumps (MAGPAC series) for this system offer various advantage compared with seal pumps for its feature leak-free, high temperautre resistant and high pressure resistant.

Introduced Products MPCP
Temperature of Liquid Normal to high temperature (+120˚F)
Application Magnet pump for test equipment of developing product”

The customer requested the performance identical to the water pump that is installed in an automobile. The testing can be carried out by installing the actual engine to the equipment, however, considering the need of temperature control, the use of a heater may give more precise results.
An MPCP stainless magnet pump was used, to take a role of a water pump. The water tank rotates synchronizing the engine.
Stepping on the accelerator pedal cause the pump to increase its speed immediately, to 7000 rpm. Releasing the accelerator pedal drops the pump speed to 1000 rpm.
The combination of a SANWA stainless magnet pump and an inverter successfully reproduced the flow rate required.

Use Example of Magnet Pump That is Integrated Into a Thermal Shock Test System for “Automobile Parts”

Outline

Pump installed ML
Temperature of liquid Low (-40˚F) to high temperature (+130˚F)
Application Magnet drive pump for environment test system

Sanwa stainless steel magnet pump allows us to transfer various temperature liquid using a single pump (one model). Previously, a number of conventional seal pumps, that have mechanical seals, were used for transferring liquid that may experience a wide range of temperature changes.

In developing automobile parts, endurance tests are made at various temperatures (heat cycle). In particular, a pump used for the heat shock test system, that reproduces difficult environments is required to endure the same hard environments.

The MAGPAC series pumps offer excellent durability in extreme temperatures, and an SiC-D bearing is employed as standard because it is a wet bearing that promises long pump service life. Therefore, the MAGPAC series pumps contribute greatly to simplify the system and reducing costs.

* SiC-D: Ceramic bearing whose surface is processed to prevent the bearing from breaking in liquid due to operation start up problems (running dry, cavitation) and thermal shock.
