All you need to know about this product

Compact stirrer in AISI 304 stainless steel (SMF5030), designed for moving and mixing liquids. The longitudinally opening structure and integrated blade promote efficient flow, improving homogenization.

Ensures effective protection against overheating under all operating conditions, including rotor lock. It safeguards the motor in situations such as: ・Plugging duty (locked rotor service) ・Rotor blockage or failure to start ・Heavy overloads ・High ambient temperature ・Ventilation system failure

Steel coated with a polyester-based thermoplastic elastomer (TPE-E), combining the mechanical strength of steel with the flexibility, chemical resistance and corrosion protection of the elastomer. This coating is ideal for use in humid or aggressive environments where durability and protection against impacts and abrasion are essential.

Ensures a secure, comfortable and non-slip grip for safe transport even in tough or wet conditions.
