How to Store and Maintain Piston Pumps to Prevent Damage to the Systems

As with any other heavy-duty or industrial machine, it is imperative to store plunger and piston pumps correctly if you use them as standby systems or for specific periods of the year only. Proper storage helps to ensure the longevity of the piston pumps even when stored long-term. Below are few guidelines to ensure the units perform as required after storage:

Where To Store

Whether plunger or piston pumps, the right location for storage is essential. The systems must be stored in a location where the units are not exposed to weather elements. Rain, dust, and sunlight take a toll on any type of equipment. As such, store the plunger or piston pumps indoors if possible, where the temperature average is reasonable. To protect the systems against debris, place the units under a canvas cover. If you don’t have indoor storage space available, keep the units under roof and canvas. It is pivotal to protect the equipment against extreme conditions, also from the heat emission associated with nearby machinery.

Protect Against Freezing

Although the temperatures rarely drop to freezing levels in South Africa, certain areas do experience extremely low temperatures during the winter. If it is at all possible that the plunger or piston pumps will be exposed to such conditions, rather be safe. Flush the units with a solution of 50/50 water and anti-freezing agent and drain the feed lines and supply facilities. If you have bought one of the Cat Pumps units from us, use the Pump Protector from the brand.

If the systems are to be exposed to high levels of humidity, apply a thin layer of protective oil lubricant to the surface areas that can corrode. However, avoid lubrication of bearings while the plunger or piston pumps are stored as grease build-up can cause harm. It is essential to safeguard the windings against moist conditions. If you can, apply power to the space heater as relevant. Also, cover the crankshaft with a thin layer of protective oil. If the systems are stored for a long period, reduce the belt tension.

If the systems are stored for several months, you need to ensure that the motor shafts are turned at minimum ten times every two months to prevent the bearings from being damaged. Keep in mind that you must also pay attention to the winding insulation of the motors. To this end, take regular readings and check for noticeable drops in the resistance. Make sure you store the motors according to the manufacturer guidelines.

Before you start the systems after a long storage period, you will need to set the O-rings and seals. Indeed, after extended storage, you may need to replace them. Also, be sure to rotate the crankshafts of the units to determine whether the operation is still smooth. Before starting up the systems, change the oil and tighten the belts again.
