Our friends over at JMP pumps sent this little nugget over today. Some good advice here if you want to prolong your pump’s impeller life, but also to ensure that your pump can perform at its best. People tend to forget basic physics when they install pumps. Pipe diameter, pressure head or lift, (the relative difference in height between the pump and the overboard discharge controls this factor). Anyhow, all of these things can be maximized if you follow the simple tips below:
TIPS FOR GOOD PUMPING
Flexible impeller pumps provide an efficient solution to most marine pumping needs. The tips below from JMP will help ensure pumps stay in top condition and operating at a high level.
Pipe runs should always be kept as short and straight as possible, avoiding rising over obstructions, as this can create air-locks. Plumbing should be reinforced, non-collapsible hose of the recommended size.
Flexible impeller pumps must not be run dry for more than 30 seconds. Bilge pumps and water pumps in particular should always be fastened to the boat structure to ensure their permanent location. Owners should mount flexible impeller pumps so that some water is left in the pump body when the pump is off. This will prolong impeller life and speed priming. Pumps must be installed with the overboard discharge well above the waterline to avoid water siphoning back into the vessel.
JMP has manufactured electro-magnetic clutch, general multi-purpose and engine cooling pumps for over 30 years. The company’s pumps can be designed to meet specific application requirements.
