Oil and Gas Long Suction Vibration

Oil and Gas Long Suction Vibration

Problem: Chesapeake Operating, Inc., a major oil and gas drilling company headquartered in Oklahoma, uses a Hydra-Cell triplex diaphragm pump (3.5” stroke, 450 rpm max speed, 27 gpm max. flow rate, 4500 psig max. pressure) to pump saltwater (1.13 sg). The pump is located over 100 feet from supply tanks. The supply line comes out of the tank, goes underground across a driveway/parking lot for more than 100 feet, then up out of the ground into the inlet of the pump. While the pump operated adequately, the pump inlet gauge fluctuated +/- 7 psig and steel pipes next to the fiberglass supply tank vibrated so violently the customer was concerned the tank would rupture.

Diaphragm Pump Failures in Soup Can Manufacturing

Diaphragm Pump Failures in Soup Can Manufacturing

Problem: A manufacturer of metal soup cans located in New Jersey uses (8) 2" air diaphragm pumps to transfer the product which is used to line the cans. The suction of the pump is attached to the bottom of a 35' tall tank. The air operated diaphragm pumps are fitted with expensive PTFE diaphragms. The diaphragms were failing prematurely which resulted in loss of product, excessive downtime, and expensive part replacement. Additionally, leakage was occurring at the pump's clamping bands and the pumps were noisy during operation.

Diaphragm Failure Causes Repeated Spills in Paint Manufacturing

Diaphragm Failure Causes Repeated Spills in Paint Manufacturing

Problem: A nationally recognized manufacturer of quality paints uses air operated double diaphragm (AODD) pumps in process and transfer applications. In this application, the AODD pumps are used in a tank storage area to transfer Texanol, a solvent-based paint additive, to the production facilities within the plant. The AODD pump sits at the bottom of a 20' high Texanol storage tank. The inlet ball valves of the pump open and close several times per second. Each time the ball valve is closed or "seated", the fluid velocity is abruptly stopped. This creates high pressure spikes or "water hammer". The force of the spike severely weakens the integrity of the PTFE diaphragms by distorting their shape with unbalanced pressure loads and concentrating stress onto one area of the diaphragm, causing cold flow. The diaphragms were lasting only three weeks before failure. Every time a diaphragm failed, production halted and solvent was spilled into the containment dike and lost.

Chemical Manufacturing Excessive Inlet Pressure

Chemical Manufacturing Excessive Inlet Pressure

Problem: A major international chemical company in New Jersey uses 3” air operated double diaphragm (AODD) pumps with PTFE diaphragms to pump a highly aggressive chemical through candle filters from an overhead tank. Part of the filtered chemical is recirculated at 30 psi back to the pump’s inlet. Rapid diaphragm failure was occurring in the AODD pumps. These pumps are generally limited to a maximum inlet pressure of 10 psi when equipped with PTFE diaphragms. As a result of the excessive inlet pressure, the PTFE diaphragms in these pumps lasted only a few hours.
