Finder - Model API 685 -Seal-Less Centrifugal Pumps
Finder can supply seal-less pumps in 0H1,0H2 and VS4 configurations. SMKM-M, HPPMD and PEPMD pumps (0H2) and HPVMD (VS4) pumps are designed and manufactured in full accordance with the API 685 (seal-less centrifugal pumps for petroleum, heavy duty chemical and gas industry, latest edition) standards. Hydraulics are directly derived from the API 610 series (SMKM, HPP and HPV) while magnetic couplings, containment devices and inner bearings have been designed to comply with the most stringent requirements of the guiding norms.
The magnetic couplings are generously sized for the applied torques and manufactured with Samarium-Cobalt elements. The primary containment shell can be manufactured in Hastelloy Cor Titanium alloy for high-pressure applications. The standard containment casing is designed to withstand the pump casing MAWP. The HPPMD series is also equipped with a compensation device to withstand axial and radial thermal expansion for smoother and more reliable operation at higher temperatures and thermal transiet conditions.
HCMD pumps (0H1) are derived from HC series and are in compliance with ISO 2858 norms.
