PRESSURE DROP = ENERGY COST

Pressure drop is an important consideration in selection and application of pipeline strainers. Pressure drop should be analyzed with respect to three basic areas:

OPERATING COST

Energy losses, which are measured as pressure drop losses, represent the cost of continuous strainer operation. If line sizes are large, or flow rates are high, these losses can be substantial.

SYSTEM PERFORMANCE

Pressure losses can impair system performance; insufficient net positive suction head can cavitate a pump. Unacceptable losses may effectively throttle flow and reduce the process stream.

STRUCTURAL INTEGRITY

Excessive pressure drop is capable of bursting or collapsing strainers. High flow rates are capable of destroying even clean, new strainers if improperly applied.
Properly designed strainers minimize the adverse effects of operating pressure drop. Design modifications or alternataive strainer styles can prove cost-effective and help avoid equipment failure/damage.

The Mack Iron Engineering Department can provide a calculated operating pressure drop for your strainer application. In addition to using nationally recognized fluid mechanics methodologies, extensive laboratory modeling by Mack's R & D has developed test data which further and more accurately describes fluid behavior in relation to the strainer.
