Question Are Rotan Pumps dimensionally interchangeable with competitive products?
Answer Yes and No. In cases where the competitive pump is a direct copy of Rotan, we obviously can supply the "real" pump. In other cases, it is highly likely that there will be a Rotan model that will "fit", and that it will have a capacity sufficiently close to the pump being replaced, so that existing drive equipment can be utilized.
Question Does Rotan supply parts for other manufacturer's pumps?
Answer No, Rotan parts are not dimensionally interchangeable with competitor's pumps. The one exception is where the competitor has "cloned" Rotan.
Question What is the direction of pumping?
Answer All Rotan pumps work equally well in both directions, and pumping direction is determined by the driver's direction of rotation. Seen from the pumpshaft end, clockwise rotation will pump from right to left and vice versa. If fitted, the relief valve should be oriented, so the part containing the spring is on the suction side.
Question Is a Rotan pump self-priming?
Answer Yes, Rotan pumps have excellent suction capabilities. When operating under low suction pressure conditions, it is always a good idea to do an NPSH calculation as part of the selection process.
Question How long will a Rotan pump last?
Answer This is highly dependent on the operating conditions and optimal initial selection of pump configuration. Rotan pumps have been known to operate continuously in excess of 30 years without maintenance when handling lubricating products. On the other hand, some installations are so arduous (viz. high degree of abrasive content), that the pumps are overhauled at intervals of just a few weeks.
Question What is the highest pressure?
Answer Again, this is dependent on many parameters. In general terms, Rotan pumps are available for system pressures up to 500 PSI and differential pressures to 300 PSI.
