Following these tests the oscillating plate (in aluminium alloy) showed signs of bad pick-up on the pump casing (also in aluminium alloy) suggesting that alternative and probably heavier material would be necessary here. Otherwise the condition of the pump was good. General Conclusions. As front page. Lov{Mr Lovesey}/AT/JB. | ||
