Neptune Expands Line Of PZ Electronic Metering Pumps To Include More Liquid End Materials



Lansdale, PA, November 2003- Neptune Chemical Pump Co., Inc. has added new liquid-end options to its line of Series PZ Electronic Diaphragm pumps. Now available are Kynar (PVDF) and 316SS liquid ends, in addition to the original PVC and Acrylic models.

The Series PZ pulse metering pump is ideal for accurate, reliable injection of a wide range of liquid materials, including chemicals, nutrients and disinfectants. The PZ pump features a revolutionary design that eliminates the need to change pump models to match the available voltage and can operate on any single phase voltage from 94 VAC to 264 VAC.

Kynar (PVDF) models are available with choice of EPDM, Viton, or Teflon seals. Stainless steel liquid ends have EPDM seals as standard; other seals are available by special order. The Kynar/EPDM and 316SS/EPDM heads on the PZ/PZi-31 models (11.4 gpd) have a discharge pressure of 220 psi for boiler chemical injection including Amine. These are also excellent choices for feeding from a basement to a roof-mounted cooling tower on tall buildings.

The Acrylic/EPDM liquid end is offered with or without an automatic air release valve to purge gas. Acrylic liquid ends are clear to allow viewing of liquid and valve action. The Acrylic/EPDM PZ's head design minimizes internal space eliminating areas where gas can accumulate, and all ports slope upward to vent gas through the top of the pump and away from the diaphragm. The CL-standard Acrylic head and the AR Acrylic head with air release valve are both excellent for sodium hypochlorite applications.

PZ models with the PVC-constructed liquid end are available with choice of Viton or EPDM seals.

Request Bulletin PZ-2003 for complete specifications on the full line, including the manual PZ Series, the control input (4-20 mA) PZi4 Series and the fully programmable PZi8 Series, plus information on Feed Verification using the Flow Checker.
