NSP/P Metering Pump

API Standard - 675

NSP/P pumps are piston metering pumps used for
high precision services with a maximum theoretical capacity that can vary linearly from 10% to 100%, allowing dosages with errors of up to 1%.

Operational Parameters

Capacity: _________________________ up to 33.600 l/h (per head)

Pressure: _____________________________ up to 350 kgf/cm2

Temperature: _______________________ -40ºC ~+400ºC

Project Features

NSP/P pumps can be used as pumps, flow meters and/or control elements.
When used as final control elements, they can be controlled remotely by process control instruments, electrically or through frequency inverters.
Designed to operate with a wide variety of products, NSP/P pumps can be used in severe chemical processes, such as pumping chemical sludge, viscous liquids, high temperatures, corrosive, flammable and toxic liquids, among others.
Pumping head: supplied in stainless steel AISI 304 or 316, HASTELLOY B and HASTELLOY C and Alloy-20.
Piston: supplied in AISI 304, 316 stainless steel and ceramic.
Piston sealing: with Teflon packing rings (lubricated by the liquid itself, or by clean liquid from an external source);
Balls: made of 316 stainless steel, HASTELLOY B or HASTELLOY C, Alloy-20, ceramic and PTFE, among other materials subject to consultation.
Special Cases: versions of heads and valves with heating chambers can be supplied, special executions for cooling and special executions can be made on request. Consult our technical department.

Advantages

Pumping heads supplied with single or double ball check valves.
Disc or cone type check valves can be fitted, with or without spring loading. (optional)
Greater performance was achieved thanks to the versatility of piston seal materials, which can be used: common grate gaskets, PTFE gaskets, PTFE “V” rings or others, according to the application needs.
Lubrication can be done by the liquid itself or by clean liquid from an external source, depending on the fluid being pumped.

Applications

The NSP/P pump series can be used in applications in the chemical and petrochemical, food, sanitation segments, among others, and can pump corrosive, toxic and radioactive liquids, subject to consultation for further information.
Remote heads: designed for applications at high or low temperatures, radioactive and explosive liquids (which must be confined in a separate cell, where only the pumping head is enclosed, and the mechanics remain standard and separate from the hydraulic system).
