PROCON's Series 1 pumps have the protection of an integral inlet strainer. The standard strainer is a 100 mesh wire screen. It traps particles that can cause serious damage to the pump. The strainer is equipped with a removable cap to allow periodic cleaning, every 4 months under normal conditions (more frequently with hard or turbid water). The clamp-on mounting style is shown in the photo; bolt-on mounting is also available.SpecificationsBody Material: Type 303 stainless steel or brassCapacity: 15 to 140 GPHNominal Speed: 1725 RPMTypical Horsepower Required: .25 to .50 HPMaximum Discharge Pressure: 250 PSIRotation (viewed from nameplate): ClockwiseDry Weight: Approximately 2.5 lbs.Dimensions: 3.56" x 3.49" x 3.86"Self Priming (water): 6 ft.
