Professional installation recommended: this is chemical dosing/injection equipment for pool water treatment (chlorine, pH adjusters, etc.) and should be installed and commissioned by a qualified pool technician.

PROXIMA PSP161 is a professional electromagnetic dosing pump with multifunctional electronics and high-level hydraulics, part of Steiel's PROXIMA PSP series. It features mechanical adjustment of stroke length (dosing volume), an internal overheating control/safety system, and a dosing chamber with anti-leakage system towards the magnet.

PSP161 is the multifunction model, with pulse and mA inputs. Operating modes include steady dosing, pulse command with dosage proportional to flow rate or automatic calculation (ppm, %, ml/q), command from a 0/4-20 mA analogue input, batch mode, and pause-work cycling.

Designed for horizontal installation, it can also be wall mounted using Steiel's rotating support bracket. Supplied with an installation kit including hoses, injection valve and foot filter.
