A Masosine SPS series pump from Watson-Marlow Pumps Group has helped to improve the efficiency and reliability of a bead mill at Fujifilm Speciality Ink Systems’ facility in Broadstairs.

The company — which manufactures speciality printing inks for products such as retail displays, textiles and CD and DVD packaging — previously used an air-operated diaphragm pump but constantly had to deal with excessive friction and heat, which had the effect of curing an important ink component, turning it from liquid to gel and ultimately leading to machine seizure.

Fujifilm decided it required a pump that generated minimal friction to avoid the associated heat problems; Watson-Marlow recommended its Masosine SPS series positive displacement pump, which is designed for industrial applications.

Key benefits of product application

  • The design of the Watson-Marlow pump features a sinusoidal rotor that overcomes the limitations of conventional rotary lobe pumps to produce powerful suction with low shear, low pulsation, gentle handling and low friction.
  • The pump offers capacity of up to 91.2m/hr and pressures of up to 15 bar, and initial trials on the viscous ink component at Fujifilm proved effective
  • The SPS pump is able to operate at very low flow speeds or around 30rev/min; this is said to be important because if the pump has a high flow rate the dwell time of the product in the machine is insufficient to be fully milled.
