Sphere Pumps & Sizing Tools

The pressure pump is designed for filling and inflating pipeline and prover spheres. As a simple, mechanical pump it is suitable for use in remote field locations and is ruggedly designed to operate reliably with minimal maintenance required.

The pump itself is a single acting, positive displacement, hand operated unit capable of pressure levels approaching 300 PSI, well above anticipated requirements.

Effective volume is approximately 4 cubic inches per stroke. Both suction and discharge sides are equipped with check valves, and a manual pressure relieving valve is included on the discharge side. The suction side of the pump is piped to standard ¼” IPS threads with a removable hard rubber reservoir. The filling hose is terminated with a quick coupling adapter designed to accept the sizing adapters used in filling spheres.

MAINTENANCE

In normal use, the pump requires no maintenance other than a few drops of oil on the roll pin bushings. For long periods of storage, pump a clean mineral oil through the pump before packing.

SIZING AND FILLING SPHERES

For efficient operation, spheres must be filled with the appropriate liquid and sized to the proper diameter. Drinkwater Products recommends a sizing ring be used to ensure that spheres are as consistent in size as possible for critical applications.

The filling accessories are illustrated in the picture below. Two styles are available, one used for the 4” & 6” Spheres, the other for the 6-1/4” and larger sizes.
