An old, noisy, energy-guzzling pump can turn your moments of relaxation into a noise nightmare, while adding to your bills.  <\/p>\n<p>At <strong>Astro Piscines<\/strong>, we have exclusively selected <strong>Pentair<\/strong> technology, the world leader in pool equipment, to equip or renovate pools in <strong>Geneva<\/strong> and <strong>Vaud<\/strong>.

With <strong>over 1,200 registered patents<\/strong>, 10,000 employees and a European manufacturing base in Pisa, Italy, Pentair is the <strong>world&#8217;s no. 1 in pool equipment<\/strong>. Pentair pumps equip Olympic-size swimming pools as well as the most demanding residential pools.  <\/p>\n<ul>\n<li><strong>Industrial quality<\/strong>: each pump is manufactured to strict standards, using glass-fibre-reinforced anti-corrosion materials.<\/li>\n<li><strong>Constant innovation<\/strong>: Pentair has revolutionized the market with variable-speed pumps that save up to 70% electricity.<\/li>\n<li><strong>Proven reliability<\/strong>: Sta-Rite and Ultra-Glas pumps are renowned for their &#8220;puncture-proof&#8221; design, with service lives of 15 to 20 years.<\/li>\n<li><strong>Guaranteed after-sales service<\/strong>: all spare parts are available in our aquastore.ch store<\/li>\n<\/ul>\n<h3>&nbsp;<\/h3>\n<h3>Our Best-Seller: The Ultraflow VS2M Variable Speed Pump<\/h3>\n<p><strong>This is our #1 recommendation for any new installation or renovation.<\/strong><\/p>\n<p>Why continue to run a pump at full speed (2,900 rpm) all the time when <strong>slow filtration is more efficient<\/strong>? The Ultraflow VS2m is equipped with a permanent magnet motor (the same technology used in electric cars) which allows you to adjust the speed to your real needs. <\/p>\n<p>&nbsp;<\/p>\n<h3>3 Reasons to Invest in a Variable Speed Pump<\/h3>\n<ol>\n<li><strong>  Golden silence (45 dB vs. 67 dB)<\/strong><\/li>\n<\/ol>\n<p>At low speeds, the Ultraflow VS2m is virtually inaudible. No more incessant whirring when you&#8217;re relaxing by the water. <strong>75% less noise<\/strong> than a conventional single-speed pump. <\/p>\n<ol start=\"2\">\n<li><strong>  Superior filtration<\/strong><\/li>\n<\/ol>\n<p>The slower the water flows through the filter, the better the filtration quality. The variable-speed pump provides <strong>continuous,<\/strong> slow-speed <strong>filtration 24 hours a day<\/strong>, with the option of switching to maximum speed for backwashing. <\/p>\n<ol start=\"3\">\n<li><strong>  Spectacular savings (-70%)<\/strong><\/li>\n<\/ol>\n<p>When flow rate is divided by 2, energy consumption is divided by 8 (affinity law). Over a 5-month season, a variable-speed pump consumes <strong>648 kWh, compared with 2,475 kWh<\/strong> for a single-speed pump. The investment pays for itself in 2-3 seasons.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;17581&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row css=&#8221;.vc_custom_1765122949167{background-color: #FFFFFF !important;}&#8221;][vc_column][vc_column_text css=&#8221;&#8221;]<strong>\ud83d\udccb Ultraflow VS2m data sheet<\/strong><\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"288\"><strong>Characteristic<\/strong><\/td>\n<td width=\"288\"><strong>Value<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"288\">Pool volume<\/td>\n<td width=\"288\">40 &#8211; 100 m\u00b3<\/td>\n<\/tr>\n<tr>\n<td width=\"288\">Power<\/td>\n<td width=\"288\">1.5 kW (2 HP) single-phase 230V<\/td>\n<\/tr>\n<tr>\n<td width=\"288\">Flow @8m HMT<\/td>\n<td width=\"288\">31 m\u00b3\/h (max)<\/td>\n<\/tr>\n<tr>\n<td width=\"288\">Programmable speeds<\/td>\n<td width=\"288\">3 speeds + manual mode<\/td>\n<\/tr>\n<tr>\n<td width=\"288\">LCD display<\/td>\n<td width=\"288\">Watts, rpm, time display<\/td>\n<\/tr>\n<tr>\n<td width=\"288\">Pentair warranty<\/td>\n<td width=\"288\">4 years parts<\/td>\n<\/tr>\n<tr>\n<td width=\"288\">Aquastore price<\/td>\n<td width=\"288\">CHF 1,850 (hardware only)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Ideal for: energy-efficient renovation, ponds close to neighbors, ecologically-minded homeowners.<\/em>[\/vc_column_text][vc_empty_space height=&#8221;5px&#8221;][vc_separator el_width=&#8221;80&#8243; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row_content&#8221; equal_height=&#8221;yes&#8221; content_placement=&#8221;middle&#8221; bg_type=&#8221;bg_color&#8221; bg_override=&#8221;full&#8221; css=&#8221;.vc_custom_1765347941866{margin-top: 50px !important;margin-bottom: 50px !important;}&#8221; bg_color_value=&#8221;#F5F5F5&#8243;][vc_column width=&#8221;1\/3&#8243; css=&#8221;.vc_custom_1772740515670{background-image: url(https:\/\/www.astro-piscines.ch\/wp-content\/uploads\/2026\/03\/Pompe-de-filtration-piscine-Pentair-par-Astro-Piscines-scaled.png?id=17610) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}&#8221; offset=&#8221;vc_col-lg-6 vc_col-md-6 vc_hidden-xs&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243; offset=&#8221;vc_hidden-lg vc_hidden-md vc_hidden-sm&#8221;][vc_single_image image=&#8221;17611&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243; offset=&#8221;vc_col-lg-6 vc_col-md-6&#8243;][vc_empty_space height=&#8221;2px&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>Rugged Classics : Sta-Rite and Ultra-Glas<\/h2>\n<p>For standard replacements or <strong>three-phase<\/strong> installations, we rely on Pentair brand legends.

If you prefer a single-speed pump, the Sta-Rite 1 HP (16 m\u00b3\/h) is sufficient for conventional filtration. <\/p>\n<p><strong>Single-speed or variable-speed pump: what&#8217;s the difference?<\/strong><\/p>\n<p>A single-speed pump always runs at maximum speed (2,900 rpm), while a variable-speed pump adjusts its speed according to your needs. The result: 70% electricity savings, 75% less noise, and better filtration as the water passes more slowly through the filter. <\/p>\n<p><strong>How much can you save with a variable-speed pump?<\/strong><\/p>\n<p>Over a 5-month season, a single-speed pump consumes around 2,475 kWh, compared with 648 kWh for a variable-speed pump. At 0.25 CHF\/kWh, this represents annual savings of around 450 CHF. The pump pays for itself in 2-3 seasons.  <\/p>\n<p><strong>When should I replace my pool pump?<\/strong><\/p>\n<p>Signs of wear: excessive noise, mechanical seal leaks, loss of flow, increased power consumption. A well-maintained Pentair pump lasts 15 to 20 years, but after 10 years it&#8217;s often more cost-effective to switch to a variable speed. <\/p>\n<p><strong>How quiet is a variable-speed pump?<\/strong><\/p>\n<p>At low speed, the Ultraflow VS2m produces just 45 dB (the level of normal conversation), compared with 67 dB for a conventional pump. You can install it near your terrace or your neighbor&#8217;s fence without creating a nuisance.  <\/p>\n<p><strong>Can a single-speed pump be replaced by a variable-speed pump?<\/strong><\/p>\n<p>Absolutely! The Ultraflow VS2m is designed to replace older Ultraflow pumps. Standard 2&#8243; fittings make for easy adaptation. Our technicians check compatibility during the free diagnostic service.   <\/p>\n<p><strong>Single-phase or three-phase: how to choose?<\/strong><\/p>\n<p>Most homes are equipped with single-phase 230V, sufficient for pumps up to 2 HP. Three-phase 400V is recommended for large installations (swimming pools &gt;100 m\u00b3, fitness centers, hotels), as it allows smoother starts and more powerful motors. <\/p>\n<p><strong>What is the warranty on Pentair pumps?<\/strong><\/p>\n<p>The Ultraflow VS2m comes with a 4-year parts warranty. Sta-Rite and Ultra-Glas are guaranteed for 3 years. All spare parts are available on <a href=\"https:\/\/www.aquastore.ch\/fr\/177-pompe-de-filtration\">aquastore.ch<\/a> for easy after-sales service.[\/vc_column_text][vc_empty_space height=&#8221;15px&#8221;][vc_btn title=&#8221;Free quote for pump replacement&#8221; shape=&#8221;square&#8221; color=&#8221;primary&#8221; align=&#8221;center&#8221; css=&#8221;&#8221; el_class=&#8221;mon-bouton-bleum&#8221; link=&#8221;url:https%3A%2F%2Fwww.astro-piscines.ch%2Fen%2Fcontact%2F|title:Contact|&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][\/vc_column][\/vc_row][vc_row css=&#8221;.vc_custom_1765122949167{background-color: #FFFFFF !important;}&#8221;][vc_column][vc_column_text css=&#8221;&#8221;] Pentair Pool Filtration Pumps: Performance, Silence and Savings The pump is the heart of your pool.
