Type T Pump
With the series type T we offer a program with several variants and constructions for the transport of almost all pumpable media.
It can be used up to maximum rotational speeds of 1500 rpm at pressures up to 16 bar. The rotational speed is basically determined by the viscosity or lubricity of the pumped medium.
At viscosities in excess of 10000 mm²/s the medium to be pumped should flow to the pump. In case of suction heights of more than 7 m LC and admission pressures in excess of 2 bar please contact our engineering department as larger piping cross sections will be required!
The pumps are driven by electric motors, backgeared motors, belt drives adjustable gear motors, or similar.
All pumps can operate with clockwise or counter-clockwise sense of rotation.
- pulsation-free pumping delivery
- independent of sense of rotation
- sturdy construction
- easy mounting
- wide selection of materials
- several sealing variants
- for packings with suction bore

Leakage free, sealless structure
The pump mechanism is the magnetic drive type. Free of leakage trouble, the pump is suitable to be incorpotated in various equipment.
Superior corrosion resistance
The wetted parts are manufactured from superior corrosion-resistant materials such as stainless steel, PPS, and PEEK. Therefore, the pump can be used to transfer various types of chemical solutions.
Long life design
Each part that is precision processed using Iwaki's original technology excels in thermal resistance, therefore does not cause pump troubles due to thermal expansion of the parts. Even when operated for long continuous hours, the pump should exhibit superior durability.
