1 - Bolted Construction
Leak-free fluid handling, bolt holes provide superior part alignment during maintenance
2 - Unique stall free air valve design
Simple, rugged and reliable lube free design
3 - Liquid Chambers
Finite Element Analysis (FEA) was used as part of the design process for maximum strength and mechanical integrity. Available in unfilled polypropylene, unfilled PVDF, 316 stainless steel and powder coated aluminum to handle the widest variety of applications.
4 - Manifolds
Single piece construction reduces chance of leakage. Computational Fluid Dynamics (CFD) optimized fluid path for optimum fluid velocities. Same material options as liquid chambers.
5 - Center Section
Plastic pumps feature glass-fiber reinforced polypropylene (GFRPP) center section construction to decrease pump weight while providing outstanding corrosion resistance. Metal pumps offer either powder coated aluminum or GFRPP center sections to reduce weight.
6 - Shaft Bushings and Diaphragm Shaft
Located in the center section the shaft bushings and diaphragm shaft are an integral part of the air control system. Bushing utilizes internal seals manufactured from a proprietary TPE material with low friction and high resiliency to provide incredibly long wear life. The stainless steel diaphragm shaft moves back and forth in the bushing over these special seals. Slots in the shaft pilot the air valve.
7 - Diaphragms
Precision manufactured diaphragms available in a variety of materials including neoprene, Buna-N, EPDM, FKM, Santoprene ™, Hytrel®, polyurethane and PTFE.
8 - Balls & Seats
Check valve balls and seats are available in a wide range of materials to provide reliable operation in a wide variety of applications.
9 - Connections
Depending upon the model, features NPT or BSP threads or universal ANSI 150/ISO-DIN PN40 flanges. 1 ½”, 2” and 3” stainless steel pumps have a 2-piece universal ANSI 150/ISO-DIN PN40 Vanstone flange option. Connection locations include end, center horizontal and center vertical.
10 - External flanged hardware
Eliminates washers simplifying maintenance and reduces the total number of parts. All fasteners are precision torqued using calibrated tools.
11 - Mounting Feet
Slotted feet with flat bottom surfaces allow for secure installation bolting.
