The side entry mixer (SEM) comprises a motor, reduction gear and propeller. The Mitsubishi SEM line is available with a choice from three basic Model, Type 3, Type 4 and Type 5, each using a high mixing performance marine propeller. In each model there is a choice between gear and belt drive and between a fixed and swivel angle propeller, allowing the customer to choose the best suited configuration for the purpose. Mitsubishi SEMs are ideal for a wide range of delicate mixing applications.

- Mitsubishi SEMs use a solid cast marine propeller.
- The mechanical seal is fitted close to the liquid in the tank to correspond to high viscosity fluids.
- Roller bearing allows operation over long periods of time.
- Pressure parts are made to a strong and durable design.
- The mechanical seal and bearing case use a unitary construction which makes for easier maintenance.
- The mixer mounting flange thickness conforms to API and JIS standards and is welded to the opening with full penetration welds.
- The spherical unit part uses double oil seals with special lip to prevent leakage of fluids.
- The hinge pin supporting the mixer is fixed by grooved nut and split pin to prevent loosening by abrasion or vibration.
- Gear drive mixers use precision machined gears for a quiet operation.
- Belt drive mixers offer the following features over gear drive models:
- Quieter operation
- Maintenance of all parts is possible without having to remove the motor.
- Requiring no gear oil, running costs are lower.
- The shut-off mechanism allows the mechanical seal and other consumable parts to be replaced while the tank is full of liquid.
Easily mounted to the manhole in the tank shell.
- MKK has delivered some 5,500 Mitsubishi SEMs to oil companies, electric power companies, gas companies and raw material producers both in Japan and overseas.
