Self Priming Pumps

SERIES ‘G’ SELF PRIMING PUMPS

Specifications

The self-priming Series ‘G’ Pump is made in either Noryl or PPS, providing a maximum range of chemical resistance. It is available with SS 316, internal hardware or completely non-metallic solution contact. The pump comes standard with 304 stainless external hardware. The pump is protected with a basket-type strainer in either PP or ECTFE. The large cover makes initial priming and removal of the strainer quick and easy. The cover is the same material as the pump or it can be ordered in clear Lexan (PCN 64-1818 90). A PP baseplate is included with close-coupled electric drive pumps.After initial prime, the Series ‘G’ Pump will lift up to 15 vertical feet (4.6m) and will remain primed even after shutdown. This pump also features an open, non-clogging impeller which is molded in conjunction with the shaft sleeve, thus isolating the shaft from solution contact. The self-priming ability, chemical resistance, light weight and basket strainer make this an ideal pump for chemical transfer, waste treatment, emergency/backup or filtering.

AIR OPERATED DIAPHRAGM PUMPS

Specifications

Here is a line of remarkably rugged and durable self-priming, double diaphragm pumps. Lube-free and non-stalling, all models will handle any product that pours, from clear water to highly viscous, abrasive and chemically aggressive materials. Proven to handle suspended solids and abrasives without damage to the product or the pump. The unique pump design utilizes far fewer parts than other pumps on the market. This results in longer operating life and easier maintenance at a lower cost. Since these pumps are driven by compressed air, there is no need for shielded electrical connections or explosion-proof motors. All models can run dry because there are no close fitting or sliding parts in the fluid section. Flow rates can be controlled to produce from zero to maximum flow simply by increasing or decreasing air flow or pressure.

Features:

• Wide selection of materials: SS, PP, AL, K, NSS – Conductive nylon N – Nylon
• 1/4″ – 2″ sizes – flows to 150 gpm
• Patented lube-free air system
• Will not stall at slow speeds
• Self-priming
• Runs dry

Material:

AL, PVDF, PP, SS316, Nylon

Performance:

1-150 gpm
