After 43 years, the built-in pump was broken, the injection molded aluminum lever was completely decomposed. The shaft on which the pump lever sits was rusted, so no VA material. All rubber parts were still fully usable. The new pump is built in and works silently against the electric pumps in boats, where the entire crew is awake when someone needs water.
First of all many thanks for the superfast delivery. Unfortunately, Whale seems to have modified this seal set and pump over the years. The two pump diaphragms do not have holes for this set to bolt to the pump. I also do not know if you can still get a corresponding spare part set. This only fits the current MK3 pumps from Whale.
I wanted to save money and had opted for a plagiarism that looks quite similar to the original by Whale. The good piece was leaking after a short time. Once again the saying 'Cheap bought means twice bought' came true.
