IWAKI CHEMICAL EAR PUMPS
Fine ceramic used in internal gear The Iwaki series chemical pump is the first internal gear pump designed for chemical process applications, in which gears of fine ceramic (SiC and Silicon nitride) are used. Our pump technology, developed over more than 0 years, has made it possible for Iwaki to equip standard pumps with fine ceramic gears. Without detracting from any of the advantages of conventional internal gear pumps abrasion, chemical, lowviscosity characteristics and sealing characteristics have been remarkably improved. In addition to the gland packing/mechanical seal type (Model X), magnetic drive sealless type (Model M) are available as standard products for an expanded range of uses. The series is an advanced gear pump, capable of dealing with a wide range of industrial processes which continue to increase in sophistication.

IWAKI CHEMICAL EAR PUMPS Both high viscosity and low viscosity liquids can be handled When a low-viscosity liquid is handled by a conventional gear pump, "jamming" and "seizing" tend to occur. SiC ceramic gears do not have this problem even when the pump functions at a high speed. Silicon nitride ceramic gears show stable performance in handling high viscous liquids, due to their strength and toughness. Ability to handle fine slurries Now that gears and other sliding components including bearings are made of ceramic, the handling of fine slurries hard and soft will not impair the longevity of these pumps. Do not specify M type for slurry applications. Performance has been noticeably improved. Ceramic gears make it possible to reduce spaces between parts, therefore outperforming conventional metal gear models. Quiet liquid transfer with less pulsation Performance comparison curves In the graph below, changes in output at varying discharge pressures are compared between the series pump and a metal gear pump. The graph shows that the series, which employs ceramics gears, is far less subject to declining output under high pressure due to its close seal clearance in the gear housing. L/min Without the pulsation that is common to reciprocating pump and general use type gear pumps, liquid is transferred quietly and smoothly no agitating or foaming. High self-priming ability Because the suction port is at the top of the pump, the pump chamber remains full when pump stops working. Self-priming is enhanced at re-start. Constant flow injection Regardless of the temperature change, viscous liquid can be handled at accurate flow rate, which cannot do with other pumps. As the output is linearly related to rpm, the flow rate is easily controlled by changing speed. Magnetic drive type added to standard line Superior anticorrosive materials such as silicon carbide, silicon nitride, alumina ceramic, PTFE, carbon and stainless steel are used in liquid ends so that all sorts of chemical liquids can be handled. M is ideal for handling chemical liquids which need strict control on liquid leakage and air contact. 0 X-2 Metal gear pump 0. MPa Improved performance characteristics M type X type 2
Construction ear housing O-ring Bearing Pinion Internal gear Port housing gasket Cover ear housing Bearing Internal gear Dowel pin Pinion Side plate O ring Operating principle A pinion (drive gear) coupled with a shaft supported by two bearings meshes with an internal gear (driven gear) whose periphery is supported by a strong bearing. Liquid is transfered by a change in the capacity of this meshed portion. In the suction process, the gears are disengaged and a space defined by the two gears and the casing expands. The liquid is drawn into the space by the negative pressure generated. In the discharge process, their teeth begin to mesh and space defined by the two gears and the casing is reduced to force out the liquid. IN OUT OUT Left or right discharge port selection 3

The output changes in proportion to rpm, but rpm should be reduced when pumping viscous liquid. Knowing required output and viscosity, the proper pump/motor rpm can be selected as in the following example. 20.0.0 STEP Mark the value of your required output (L/min) on the scale on the left, and draw a horizontal line to the right. Output (L/min).0 1.0 0. STEP Mark the value of your viscosity (00mPa s) on the scale at the top and draw a line downward. In the event your viscosity falls in the middle of two scale lines, select the line on the left (the higher value). STEP Extend the intersected point to the left horizontally until intersecting the first pump line (X/M-2). This point specifies pump.
