87 SERIES METERING PUMP / CHEMICAL METERING PUMP

BENEFITS

• External lubrication free
Plunger packing design eliminates the need for external lubrication

• Space critical Design
Compact physical size

• Simple check valve servicing
Easily disassemble

• Low operation costs
Small volume piston design uses less actuation gas

• Timer reliability
Pneumatically actuation timer utilizes diaphargms for lubrication –free repeatable performance

• Repeatable
Positive displacement plunger design ensures repeatability

• Safe
Intrinsically safe pneumatic design

• Corrosion resistance
Manufactured en stainless steel 304 and 316

• Longer piston seal life
Exactly 90 grades machined threaded, plunger/piston assembly eliminates irregular wear on the plunger seal

• Reliable
Fewer moving parts

• Proportional to flow and batch control option
