Self-priming pump

The Contractor Pump range from AllightPrimax is designed for cost-efficient fluid handling. Fuel usage is minimized through the hydraulic pump-end, impeller and wear plates. The self-priming pumps do not require manual priming of the suction line or filling of a priming tank to begin normal operation. The pumps can run dry for extended periods due to the oil bath mechanical seal assembly, which allows priming with long suction hoses and suction lifts up to 28 feet. As fluid levels fluctuate, the pumps will snore until the liquid is available to fully re-prime automatically. 803/328-2035; www.allightprimax.com.

Relief valve

The Pneumatic Dynamic Lifter from Singer Valve is a responsive, compact sewage relief valve that can handle high pressures and uses a compressed air cylinder to hold the valve closed. The chamber is fitted with a relief pilot that is closed when line pressure is lower than the set point. If the pressure rises above the set point, the relief point opens, causing the air in the cylinder to vent, opening the valve. The valve closes drip-tight when pressure falls below the set point.

The surge anticipator has two three-way solenoid valves to put air into the cylinder under the piston, driving the valve open on power failure. When the surge returns back to the pump, it comes back to an open valve where it can be discharged back to the sump in the vicinity of the pump. The main valve needs to be open long enough to handle the initial surge, but not longer, or it will continue to drain the line. The solenoid is on a timer, which is set at startup. Once the set time has elapsed, another solenoid allows air to recharge the cylinder, closing the main valve. 604/594-5404; www.singervalve.com.
