Fresh water s u p p l i e s at s ea
Gilbert Gilkes & Gordon has met t he r e q u i r e m e n t s of m a r i n e e q u i p m e n t manufac tu re r Ham- wor thy Marine, to supply eight T-Series ver t ical in-line centri- fuga l p u m p s f o r c i r c u l a t i n g fresh water on board a ship.
l i a m w o r t h y M a r i n e a p - p roached Gilkes to supply the p u m p s for this cus tomer appli- cat ion as they did not have this p a ~ i c u l a r uni t wi thin its own range. Opera t ing with a pres- sure of 25 m3/h with a total head of 55 m via hor izon ta l p ipes , t he p u m p s are f i t t ed and driven by 11 kW ABB elec- tric motors at 1750 rpm and braced by a spacer coupling.
The ro ta t ing assembly can be r emoved w i t h o u t d i s m a n t l i n g the p u m p or electric motor . As the p u m p opera tes as a ver t ical unit , v i ta l space savings are achieved in the res t r ic ted space on board.
Self Priming is not a normal f e a t u r e of t he T -Se r i e s bu t where wate r needs to be raised upwards, a self pr iming act ion is requi red to bleed the p u m p of air. In o rder to make the p u m p s self-priming, Hamwor thy sup- plied its own special au tomat ic air e jector primers.

G l a s s f l a k e coat ing pro tec t s e f f luent sump
A high pe r fo rmance glass flake coat ing, supp l i ed by ITW Ir- a thane, has been employed to pro~ide pro tec t ion agains t cor- rosion in a 30 m 2 effluent sump at D r a x Power s t a t i on , t he largest single coal-fired p lan t in the UK.
The concre te sump is used to col lect t he d i lu t ed acid and a lka l i r e - g e n e r a t i o n l i q u o r s from the power s ta t ion ' s wa te r t r e a t m e n t plant.
The internal surface area of the sump was lined with a spray- applied, glass reinforced Epoxy Vinyl Ester system, selected as it possesses long- te rm chemica l resistance characteristics.
The p roduc t is manufac tu red using the glass flake coat ing t echnology of the Fuji Resin Company, Japan .

[ ] Lubricant conserva t i on gets a b o o s t
Auto-Masters of Cheshire, UK, has instal led a progressive cav- ity p u m p manufac tu red by Li- quid Movers to reduce the loss of cooling and lubr icant l iquid wi th in a vacuum box.
Auto-Masters has a regular o rde r to m a n u f a c t u r e a lumi- n ium coupl ing p la tes for a t tach- m e n t to r u b b e r f u e l b a g s instal led on Tornado jets. To produce a number of coupl ings f rom a large single sheet of a luminium, the sheet is held down by v a c u u m whi l s t t he cu t te r cuts the forms out. The coolant and lubr ica t ion l iquid would normal ly go to waste. To reduce this wastage, Auto-Mas- ters has connec ted the progres- sive cavity p u m p to the cabinet holding the vacuum box which then works agains t the vacuum and ex t rac t s the excess liquid. The p u m p t h e n r e t u r n s t he l iquid to the main reservoir to be recycled th rough the process.
Other types of p u m p were t r ied but the swarf works its way in to t he p u m p caus ing damage and loss of p roduc t ion whils t the p u m p was repai red or rep laced . Swarf does not damage the ro tor or s ta tor of the Liquid Movers' p u m p ensur-
