These pumps were developed to take maximum advantage from the key features of a group of synthetic thermosetting resins. The resins used are characterised by excellent resistance to chemical attack, strength and hardness comparable with many metals, and a good resistance to abrasion from fluid borne abrasives. A range of resins is used to gain optimum chemical resistance to the many fluids and chemicals encountered in industry.
The Pacifichem product provides then a cost-effective alternative for many processes which would normally require the use of exotic metal alloy or plastic lined pumps. Equally, other more innocuous but nontheless troublesome fluids such as chlorinated water and seawater are handled with ease and with useful economy.
1 / CLOSE COUPLED PROCHEM
CLOSE COUPLEDReliability has long been accepted as being inversely proportional to the number of components in any system. Quality close coupled pumps have used this principle to improve reliability in many industries and over the last 10 years Pacifichem have been successfully using the configuration in 90% of the toughest chemical duties. The Mk II close coupled provides a cost effective, compact solution to most industrial chemical applications
2 / LONG COUPLED PROCHEM
LONG COUPLEDFor many operators the use of any but this traditional layout is not an option. The ability to separate the hydraulic and prime mover elements provides tempting convenience and economy for many large sites. Pacifichem assist the cause of those choosing to hold with tradition by providing power-end and base plate in the same corrosion resistant resins as the wet-end.
3 / BELT DRIVEN PROCHEM
BELT DRIVENEven in the 21st century belt driving pumps carries advantages for some, with more accurate tailoring of curves to duties and the option of readily revising curves for those changing or indeterminate duties that make final decisions so difficult. Advantage is also to be derived from the safety from flooding that an overmounted belt drive can provide in bund installations.
4 / CHEMICAL ROAD TANKER
CHEMICAL ROAD TANKERThe Pacifichem road tanker pump provides the chemical transport industry with a pump package that will handle almost any chemical they need to move. Driven by either a premium brand 13hp petrol engine or a hydraulic motor and PTO package, this pump represents the most cost effective and reliable solution to an extremely difficult duty
5 / VERTICAL SPINDLE PROCHEM
VERTICAL SPINDLEThe VS series vertical spindle pump has a specialised role in chemical pumping. Because this pump operates with its volute and impeller immersed directly in the supply or process tank. It is often the most convenient method of achieving NPSHR in challenging applications. The absence of a mechanical seal means that the VS will happily run without product, making it particularly convenient for those processes in which it is difficult to guarantee reliable process fluid supply.
This feature can even be utilised to advantage in those circumstances where top access to a tank is not available, by side-mounted hard-piping of the pump to the tank at an appropriate level. This unit is, of course, produced with all wetted components in our thermosetting synthetic resin materials and is available in a useful range of sizes.

Our most demanded pump is the close coupled MkII. This robust pump is of end suction back pull-out design and provides the compact simpicity of a close coupled pump without compromising reliability. Great care has been taken to ensure that the impeller to bearing-set relationship provides excellent rotating assembly, while the standard use of a premium quality electric motor ensures optimal thrust control and good bearing life and maximises mechanical seal performance.
Of primary importance in a chemical pump, all wetted parts are in our corrosion resistant thermosetting resins and all non-motor fasteners are in stainless. An added feature which improves reliability and longevity in harsh environments is the use of resin for motor adaptor and base and the installation of a resin labyrinth to protect the motor.
