- Caster born in Italy in 1976.
- Along with “Acciaierie Valbruna” facilities, from raw materials to metallurgical and science laboratories were available.
- Five basic alloy magnetic-drive Sealless pump models were designed and developed simultaneously, including centrifugal and regenerative turbine and thermoplastics, along with vane pumps.
- Machining from solid block, slab and bar was selected over casting and injection moulding whenever feasible.
- Additional four basic designs quickly followed including alloy and thermoplastic self-priming centrifugal, self-priming thermoplastic regenerative turbine and thermoplastic sliding vane positive displacement models.
- 1985 Caster design and develop oscillating piston pump for high viscosity.
- 1988 First double stage pump was designed and installed. First stage centrifugal impeller, second stage regenerative turbine impeller.
- 1988 Design and developed barrel centrifugal multistage pump. First multistage pump barrel, magnetically driven.
- 2000 Sundyne Corporation acquired Caster facility in Italy.
- 2005 Production is moved from Italy to England into HMD/Kontro (a company of Sundyne corporation group) facilities.
- 2009 ownership production and distribution of Caster product and relevant spare parts, is officially given from HMD/Kontro to Greenpumps srl.
