A – Yes, any positive displacement pump will develop a dangerously high pressure, if run with the discharge throttled or shut off. If an isolating valve is fitted to the suction pipework (or if it is possible for an excessive head to be imposed on the pump by any other cause), then the pump must be fitted with a pressure relief valve, which is available as an option on all sliding shoe pumps.
