Head
Vertical distance between the intake level of a pump and the discharge level. Expressed in liquid column meters or bars (pressure). In this case, the liquid being pumped does not exceed any difference of level, but is distributed at ground level at a given pressure: Symbol: H.

HYTREL®
HYTREL is Du Pont’s registered trademark for its range of technical thermoplastic elastomers.
Properties and characteristics:
HYTREL is a thermoplastic elastomer for engineering applications which combines many of the most interesting characteristics of elastomers and the high performance of flexible thermosplastics.
HYTREL in fact possesses an exceptional toughness and elastic return; a high resistance to “creeping”, to shock and to stress when flexed; it has an excellent flexibility at low temperatures, while maintaining rather well its properties at high temperatures.
It is also resistant to the attack of many industrial chemical substances, oils and solvents.
