Griswold Series H Self Priming Centrifugal Pumps are designed to lift water (up to a maximum of 25 feet). The H Series are able to maintain a prime even where check valves or foot valves have failed. The suction line is located higher on the pump housing than other pumps which keeps the impeller and mechanical seal covered with water at all times eliminating the need to re-prime the pump and protects the seal from running dry and costly replacements. The H Series pumps are available in two versions. The HL pumps are designed for higher pressures at lower flows with lower horsepowers. The HH pumps are designed for higher flows at higher pressures requiring higher horsepowers.
Take a Look at These Features:
Fast, Positive Priming: Pressures in the case and in the volute are balanced during pumping, preventing any loss of capacity from recirculation. In operation, you get maximum pumping capacity at the lowest cost.
Semi-Open Type Impeller: High efficiency, semi-open type impeller with clearance easily adjustable to compensate for wear after extended service, even with abrasive liquids.
Mechanical Shaft Seal: The open type mechanical seal is the finest available. All metal parts are chrome nickel stainless steel. The stationary seal face is made of optimum grade ceramic, resiliently mounted. The self-lubricating carbon rotating seal face assures longer, more reliable operation with a minimum of wear.
Heavy Duty Case: Highest quality, close grain cast iron case construction features thick wall sections for more rugged operation under adverse pumping conditions. Yet the entire pump is amazingly lightweight.
Perfect Alignment: A heavy-duty rigid bracket maintains perfect alignment between the centrifugal pump and the motor.
