Each stage adds pressure to the same flow, so a tall, narrow pump does work that would otherwise need a much larger single-stage machine.

Grundfos launched the CR30 in 1971 as the first inline multistage centrifugal pump made, with the inlet and outlet at the same level and the same size.

Acids and alkalis, ultra-filtration, reverse osmosis, softening and demineralising, and distillation are all CRN duties, and the CR is not listed for any of them. Chloride-bearing water goes on the CRN too, below 30°C and up to 500 ppm. Firefighting runs the other way: the CR is listed for it and the CRN is not.\u003c\/p\u003e\n\u003cp\u003eSo if the medium is clean water and always will be, the CR is the pump and the stainless is money you do not need to spend. If there is anything in the water that will find the 304, pay for the CRN once rather than re-piping a corroded base later. The awkward cases are the ones where the medium changes with the season or with a cleaning cycle, and those are worth a phone call rather than a guess.\u003c\/p\u003e\n\u003cp\u003eOne more version worth knowing.

The customer states a flow. The consultant adds margin for future duty, the contractor adds a little more, the installer rounds up again. Nobody in that chain is careless and the pump that comes out is far too big. You then carry an oversized motor for the life of the installation, and on a multistage pump running past the end of its curve you get the worse problem: not enough back pressure, cavitation, and a shaft seal that goes early.\u003c\/p\u003e\n\u003cp\u003eThe other one is suction.

Trimming an impeller to a fixed duty point lowers efficiency against the full diameter, so an oversized pump trimmed back is not the same as the right pump run whole.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection\u003e\n\u003ch2 class=\"text-[24px] font-semibold tracking-tight\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"mt-4 overflow-hidden rounded-lg border border-slate-200\"\u003e\n\u003ctable class=\"w-full border-collapse text-left\"\u003e\n\u003ctbody class=\"divide-y divide-slate-200\"\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003ePump type\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003eVertical multistage centrifugal, inline ports, non-self-priming\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003eSizes\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003eCR 1s, 1, 3, 5, 10, 15, 20, 32, 45, 64, 95, 125, 155, 185, 215, 255\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003e16 flow sizes, each with a range of stage counts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003eFlow rate\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003e0.3 to 330 m³\/h\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003eCR 1s minimum to CR 255 maximum, 50 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003eHead\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003eup to 362 m\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003erange maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003eMaximum operating pressure\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003e10 to 40 bar\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003eby size and connection;

If none of those is true, a CRE is money spent on control you will not use. A transfer duty that runs flat out into a tank does not vary, and a fixed-speed CR with a starter is the cheaper pump with less to go wrong.\u003c\/p\u003e\n\u003cp\u003eThe other check is where the pump lives. Putting the drive on the motor puts the electronics in the plant room, at whatever temperature and altitude the plant room happens to be. Grundfos calls for an oversize motor above 50 °C ambient or above 1000 metres, which is the sort of derate that turns a straightforward selection into a bigger frame size. Tell us the ambient and the site altitude when you enquire.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection\u003e\n\u003ch2 class=\"text-[24px] font-semibold tracking-tight\"\u003eHow the Grundfos CRE works\u003c\/h2\u003e\n\u003cdiv class=\"mt-3\"\u003e\n\u003cdiv class=\"prose max-w-none prose-slate prose-p:text-slate-600 prose-headings:text-navy prose-headings:font-semibold prose-headings:tracking-tight prose-a:text-marine prose-a:no-underline hover:prose-a:underline prose-strong:font-medium prose-strong:text-navy prose-li:text-slate-600 prose-blockquote:border-l-2 prose-blockquote:border-marine prose-blockquote:pl-5 prose-blockquote:font-medium prose-blockquote:not-italic prose-blockquote:text-navy [\u0026amp;_blockquote_p]:text-navy [\u0026amp;_blockquote_p:first-of-type::before]:content-none [\u0026amp;_blockquote_p:last-of-type::after]:content-none prose-p:text-[15px]\"\u003e\n\u003cp\u003eA stack of impellers, each in its own chamber, adds pressure to the same flow. That is how a tall, narrow pump reaches 262 m of head. The CRE is not self-priming, so the inlet has to be flooded.\u003c\/p\u003e\n\u003cp\u003eThe E-motor is what makes it a CRE. Grundfos builds the MGE as a totally enclosed, fan-cooled motor with a frequency converter in the terminal box and a PI controller behind it. On a pump ordered with the integrated pressure sensor, the sensor on the outlet feeds pressure back to the controller, the controller compares it with the setpoint and the converter trims motor speed until the two agree. Because that runs continuously, the pressure in the pipework stays put while the draw on it changes. Two control modes ship on the pump: constant pressure, which is the factory setting, and constant curve.\u003c\/p\u003e\n\u003cp\u003eOrder a CRE without the sensor and you get open-loop speed control, or a pump ready for a sensor you fit later. That variant covers flow, level, temperature, differential pressure and differential temperature control, and it is also the one to specify when a remote analogue signal sets the speed from a building management system.\u003c\/p\u003e\n\u003cp\u003eProtection is inside the converter rather than the panel. The MGE carries thermal protection against slow overload and blocking, and Grundfos states that E-pump installations do not require a motor-protective circuit breaker, only normal short-circuit protection for the cable. Motors from 3 to 26 kW include a Bluetooth module that talks to Grundfos GO at up to 10 metres; pumps from 0.37 to 2.2 kW are factory-fitted with the FM300 functional module, which brings three analogue inputs, two Pt100\/1000 inputs, two LiqTec sensor inputs and two signal relays for anyone wiring the pump into a wider control scheme.\u003c\/p\u003e\n\u003cp\u003eOn efficiency, Grundfos rates the MGE motor at IE5 level from 0.37 to 26 kW, and states that the product complies with the ecodesign requirements for water pumps in the ErP Directive, Commission Regulation (EC) No 547\/2012. The hydraulic side is measured by the Minimum Efficiency Index, and the benchmark Grundfos quotes for the most efficient water pumps is MEI ≥ 0.70.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection\u003e\n\u003ch2 class=\"text-[24px] font-semibold tracking-tight\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"mt-4 overflow-hidden rounded-lg border border-slate-200\"\u003e\n\u003ctable class=\"w-full border-collapse text-left\"\u003e\n\u003ctbody class=\"divide-y divide-slate-200\"\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003ePump type\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003eVertical multistage centrifugal pump with integrated frequency converter\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003enon-self-priming, in-line ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003eMaximum flow\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003e240 m³\/h\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003eCRE 155 maximum, 50 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003eMaximum head\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003e262 m\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003erange maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"bg-white\"\u003e\n\u003cth class=\"w-[30%] bg-slate-50\/60 px-5 py-3.5 align-top text-[13px] font-medium text-slate-500\"\u003eMaximum operating pressure\u003c\/th\u003e\n\u003ctd class=\"px-5 py-3.5 align-top text-[14px] font-medium text-navy\"\u003e30 bar\u003c\/td\u003e\n\u003ctd class=\"w-[22%] px-5 py-3.5 align-top text-[13px] leading-relaxed text-slate-500\"\u003eCRE 32-6-2 to 32-10-2 and CRE 45-5-2 to 45-7, PJE, clamp, union or DIN connection;
